Moving a WordPress site sounds simple until something breaks halfway through. The right migration plugin makes the difference between a smooth handoff and a frantic support ticket at 2 a.m. Here are the top picks by situation:
- Best overall: Duplicator Pro — reliable, full-featured, handles most use cases
- Best completely free option: Migrate Guru — server-side, no size limits on the free plan, handles sites up to 200 GB
- Best for developers: WP Migrate Pro — push/pull workflow, precise DB control, WP-CLI support
- Best backup + migration combo: UpdraftPlus — migration now included in the free version
- Best for large sites on shared hosting: Migrate Guru — runs on its own servers, bypasses PHP memory limits
- Best for multisite networks: Duplicator Pro or All-in-One WP Migration (with extension)
- Note: If you’re on Kinsta, skip All-in-One WP Migration — it’s banned on their production environment
What to Look For in a WordPress Migration Plugin
Not all migration plugins work the same way — and not all of them work well under the same conditions. Before picking one, it helps to know what actually matters when moving a WordPress site.
Ease of use. A tool that requires manual FTP uploads and phpMyAdmin commands is fine for developers. It’s a disaster for a small business owner doing their first migration. Match the tool to your comfort level.
File size limits on the free plan. Several popular plugins restrict what you can import on the free tier. All-in-One WP Migration caps imports at 512MB unless you pay for an extension. If your site is larger than that, you’ll hit a wall.
Host compatibility. Some managed WordPress hosts block certain plugins outright. Kinsta bans All-in-One WP Migration on production servers because it abuses disk I/O. SiteGround has its own dedicated migration plugin. This is not widely documented in most comparison articles.
Backup before migration. A migration is not a backup. If something goes wrong mid-transfer, some plugins leave your destination site in a broken state. Plugins with built-in backup or rollback features give you a safety net.
Serialized data handling. WordPress stores certain settings — widget configurations, theme options, plugin data — as PHP serialized strings. A naive search-and-replace on an SQL export file will corrupt these strings silently. Good migration plugins detect and handle serialized data correctly.
Multisite support. If you’re running a WordPress multisite network, most migration plugins either fail or require a premium extension. Only a handful handle this reliably.
Three Migration Architectures — Which One Is Running Under the Hood
Most guides list features without explaining how the plugin actually moves your data. There are three distinct approaches, and they have very different implications for shared hosting users.
Export/Import (package-based). The plugin packages your entire site into a single archive file on the source server, then uploads it to the destination. This is how Duplicator and All-in-One WP Migration work. The problem: the source server needs enough disk space and PHP memory to create the package. On resource-limited shared hosting, this is where timeouts happen.
Server-side (external infrastructure). The plugin connects to an external server (the plugin provider’s own infrastructure) which pulls your site data and pushes it to the destination. Your source server is barely involved. This is how Migrate Guru works — powered by BlogVault’s servers. It’s why Migrate Guru can move a 200 GB site on 128MB of shared hosting without breaking a sweat.
Push/Pull (direct site-to-site). The plugin connects two WordPress installations directly. You push data from one to the other in real time — no archive file created. This is the WP Migrate approach, built for developers who need to sync databases between localhost, staging, and production repeatedly.

1. Duplicator — Best Overall for Most WordPress Users
Duplicator has been around for over a decade, and for good reason: it handles the full migration lifecycle without requiring the user to know anything about SQL or FTP. The free version covers basic migrations. The Pro version adds a guided Migration Wizard, cloud backup destinations, and one genuinely unique feature — it can install WordPress at the destination for you. No other major migration plugin does this.
What Duplicator Does Well
- Two-step Migration Wizard in the Pro version — minimal technical knowledge required
- Only plugin that installs WordPress at the destination from scratch (no pre-install needed)
- Reusable site packages — configure once, deploy to multiple locations (useful for agencies)
- Server-to-server import: pull packages directly from a URL without downloading to desktop first
- Cloud backup storage: Amazon S3, Google Drive, Dropbox, OneDrive
- Rollback recovery points for post-migration safety
- 1,000,000+ active installs, 4.9/5 rating on WordPress.org (4,860 reviews)
Duplicator Limitations
- Not server-side — source server must have enough disk space and memory to create the package
- Multisite support is Pro-only
- Free version has reduced site size and feature limits
- Failed storage-constrained test (99% disk) in independent testing
Who Should Use Duplicator
Freelancers and agencies building client sites who need both migration and backup in one tool. Anyone doing a one-time host move who wants a guided, low-stress process. Users who need to deploy the same site setup to multiple locations.
Who Should Skip Duplicator
Users on shared hosting with very limited disk space — the package creation step requires free space equal to the site size. Developers who need push/pull workflow with precise database control (WP Migrate is better for this). Anyone who needs a migration under 128MB of available server memory.
Pricing: Free plan available. Pro Basic: $79/year (2 sites). Pro Plus: $199/year (5 sites). Pro: $399/year (20 sites, includes multisite). 14-day money-back guarantee.

2. Migrate Guru — Best Free Plugin for Large Sites
Migrate Guru is the outlier in this space: it’s completely free, there’s no premium tier, and it does one thing well — moving large WordPress sites without putting any load on the source server. It’s powered by BlogVault’s server infrastructure, which means the migration processing happens remotely while your source site continues running normally.
What Migrate Guru Does Well
- Completely free — no subscription, no upsell, no paid tier
- Server-side processing: runs on BlogVault’s servers, not yours
- Handles sites up to 200 GB
- Bypasses PHP memory limits and execution timeouts on shared hosting
- Automatic URL rewriting and serialized data handling
- Works with 5,000+ web hosts
- 100,000+ active installs, 5/5 rating, 1,608 reviews on WordPress.org
- Email status notifications throughout the migration
Migrate Guru Limitations
- This is NOT a backup plugin — it does not create backups
- Does not support localhost/local development environment migrations
- 5 site migrations per user per month (each site can be moved unlimited times within that)
- No atomic restore feature
- Limited multisite support (cannot migrate multisite subsites to a different domain)
- No WP-CLI support
Who Should Use Migrate Guru
Anyone who needs to move a large site (WooCommerce store, media-heavy portfolio, news site) and doesn’t want to pay. Users on resource-limited shared hosting where other plugins time out. Site owners who need to move the same site multiple times to find the right host.
Who Should Skip Migrate Guru
Anyone who thinks “migration” means “backup” — it doesn’t here. Developers working in localhost environments (not supported). Anyone who needs multisite network migration.
Pricing: Free. No paid tier exists.
3. All-in-One WP Migration — Best for Simple, Beginner-Friendly Moves
With 5 million+ active installs and a track record going back to 2013, All-in-One WP Migration is the most-installed migration plugin in the WordPress ecosystem. It’s simple, it’s reliable for standard migrations, and it handles cross-database migrations (MySQL to SQLite and back) that no other major plugin does out of the box.
The catch: the free version’s 512MB import file size limit trips up a lot of users who didn’t read the fine print. Many sites exceed this, especially those with image-heavy media libraries.
What All-in-One WP Migration Does Well
- 5,000,000+ active installs — battle-tested at massive scale
- Drag-and-drop import interface — no command line needed
- Cross-database migration: MySQL, MariaDB, and SQLite supported
- WP-CLI support for command-line automation
- Trusted by Boeing, NASA, Harvard, Stanford, and Automattic
- WCAG 2.1 AA accessibility compliance
- Available in 50+ languages
- Updates every two weeks — actively maintained
All-in-One WP Migration Limitations
- Free version has a 512MB import file size limit — you need the Unlimited Extension ($69) for larger sites
- Banned on Kinsta production servers (disk I/O instability per Kinsta’s sysadmin team)
- User reports of hanging on Bluehost imports in some configurations
- No connection interruption recovery — if the network drops, you start over
- Had CVE-2025-8490 (Stored XSS vulnerability in file upload, patched in v7.98, August 2025) — update if you haven’t
See the All-in-One WP Migration full review for more on the extension pricing and use case breakdown.
Who Should Use All-in-One WP Migration
Beginners who want the simplest possible interface. Small sites under 512MB on non-Kinsta hosting. Anyone doing cross-database migrations (SQLite to MySQL is a specific niche it handles well). WordPress Playground users (SQLite integration is built in).
Who Should Skip All-in-One WP Migration
Kinsta users — it’s banned on their production servers. Sites larger than 512MB on the free plan. Anyone needing connection interruption recovery. Users on Bluehost who’ve encountered import hang issues.
Pricing: Free (512MB cap). Unlimited Extension: from $69. Pro (includes Unlimited): from $99. Multisite Extension: from $319.
4. UpdraftPlus — Best When You Want Backup and Migration in One
UpdraftPlus made a significant change in August 2023: migration is now included in the free version. Before that, you needed a paid Migrator add-on. The free version now lets you back up the source site and restore it on a new host with built-in search-and-replace for URL updates. The premium version adds direct site-to-site transfer, selective migration of specific components, and more cloud storage destinations.
In independent stress testing, UpdraftPlus was the standout performer — surviving storage-constrained environments (only 1% free disk), connection interruptions mid-migration, and handling large databases under 2 minutes. No other plugin in the same test matched it across all categories.
What UpdraftPlus Does Well
- Backup-first approach — creates a safety net before moving anything
- Migration now included in the free version (since August 2023)
- Survived 99% disk-full conditions and connection cut-outs in real-world testing
- Incremental backups save storage and processing time
- Broad cloud storage support: Dropbox, Google Drive, Amazon S3, OneDrive, Backblaze, Azure, and more
- Multisite support
- 3,000,000+ active installs, 4.9/5 rating
UpdraftPlus Limitations
- Free version migration is manual (backup on source, upload and restore on destination) — not a single-click direct transfer
- Premium required for direct site-to-site migration without intermediate file download
- Premium required for selective migration (choose specific plugins, themes, DB tables)
- Not a push/pull developer tool — not suited for frequent DB syncs
Who Should Use UpdraftPlus
Site owners who want one plugin handling both ongoing backups and occasional migrations. Anyone on constrained hosting where other plugins time out. Users who want an automatic safety net created before any migration attempt.
Who Should Skip UpdraftPlus
Anyone doing a one-time, completely free migration who doesn’t need backups at all — Migrate Guru is simpler for that. Developers needing push/pull database workflow.
Pricing: Free (backup + basic migration). Premium: from ~$70/year. Migration is now free since v1.23.8.
5. WP Migrate — Best for Developers Doing Frequent DB Moves
WP Migrate (formerly WP Migrate DB Pro, developed by Delicious Brains, now part of WP Engine) is built for a specific workflow: pushing and pulling WordPress databases between localhost, staging, and production environments. It’s not a traditional full-site migration tool — it’s a developer precision instrument.
The free Lite version exports the database as a SQL file with find-and-replace built in. The Pro plans add real-time push/pull between connected sites, media file sync, theme and plugin file transfer, and WP-CLI integration for automation.
If you’re setting up a local dev environment, the guide to WordPress local development tools covers LocalWP and alternatives.
What WP Migrate Does Well
- Push/pull workflow — move data directly between two connected WordPress sites
- Precise serialized data handling — no corruption on find-and-replace
- Granular control: choose exactly which database tables to include or exclude
- WP-CLI integration for scripted, automated migrations
- Officially recommended by Local (WP Engine’s local development tool)
- Faster than FTP for media file sync
- Non-profits: 50% discount available. Teachers: complimentary Platinum license.
WP Migrate Limitations
- Under stress testing with large file-heavy sites, media and theme/plugin file migration failed
- Not beginner-friendly — the interface assumes developer familiarity
- Free Lite version is DB export only — no push/pull, no media sync
- Requires plugin installed on both source and destination sites
Who Should Use WP Migrate
WordPress developers maintaining local → staging → production workflows. Agencies doing daily or weekly database syncs. Anyone using WP Engine’s Local tool for development. Developers who need WP-CLI integration for deployment scripts.
Who Should Skip WP Migrate
Beginners or non-developers. Anyone doing a one-time host migration with large media files. Users who need a free, complete site migration without technical setup.
Pricing: Free (Lite, DB export only). Basic: $49/year (1 site, DB only). Standard: $99/year (2 sites, DB + WP-CLI). Plus: $189/year (3 sites, DB + media + files). Premier: $219/year (unlimited sites, all features including multisite).
6. Solid Backups — Best for Complex Agency and Multisite Setups
Solid Backups (formerly BackupBuddy, from SolidWP, previously iThemes) has protected WordPress sites since 2010. It’s not the right tool for a beginner doing a one-time migration, but for agencies managing complex client sites with strict uptime requirements, it’s worth the price of admission.
What Solid Backups Does Well
- Incremental backups minimize storage usage and processing time per backup cycle
- Automatically updates internal links and file references after migration — prevents 404 errors post-move
- Handles domain changes and subdomain migrations cleanly
- Built-in error handling and rollback
- Multisite support
- Can store backups locally or in remote storage (Amazon S3, Dropbox, Google Drive, etc.)
Solid Backups Limitations
- No free plan — entry price is $99/year
- Overkill for simple one-time migrations
- Interface less intuitive than Duplicator or All-in-One for beginners
Who Should Use Solid Backups
Agencies managing multiple client sites with strict backup and migration schedules. Developers who need reliable incremental backups and migration in one tool. Complex multisite setups requiring fine-grained control.
Who Should Skip Solid Backups
Single-site owners doing a one-time migration — there are cheaper or free options that do the job. Budget-conscious users — no free tier means you pay from day one.
Pricing: Basic: $99/year (1 site). Plus: $199/year (5 sites). Agency: $299/year (10 sites). Also available bundled in SolidWP Suite.
Host Compatibility — What Works Where
Most migration plugin guides ignore a critical real-world constraint: some managed WordPress hosts actively block specific plugins. Using the wrong one wastes hours and can leave your site in a broken mid-migration state.
| Plugin | Kinsta | SiteGround | Bluehost | LocalWP (WP Engine) | General Hosts |
|---|---|---|---|---|---|
| Duplicator | Yes | Yes | Yes | Yes | Excellent |
| Migrate Guru | Yes | Yes | Yes | No (no localhost) | Excellent |
| All-in-One WP Migration | Banned (production) | Yes | Issues reported | Yes (DevKinsta local only) | Caution on managed hosts |
| UpdraftPlus | Yes | Yes | Yes | Yes | Excellent |
| WP Migrate | Yes | Yes | Yes | Officially recommended | Excellent |
| Solid Backups | Yes | Yes | Yes | Yes | Good |
| SiteGround Migrator | No | SiteGround only | No | No | SiteGround-only (free) |
A note on Kinsta: All-in-One WP Migration is on Kinsta’s banned plugins list because it “runs up a huge amount of disk space and can abuse disk I/O which can cause platform/LXD instability” — per Kinsta’s own support team. If you’re on Kinsta, use Duplicator, Migrate Guru, UpdraftPlus, or WP Migrate instead.
A note on SiteGround: If you’re moving to SiteGround, their own free SiteGround Migrator plugin handles the transfer with zero configuration. You generate a token from your SiteGround hosting panel and paste it into the plugin on your source site. That’s it.
If you’re still deciding on a host, the best managed WordPress hosting comparison covers Kinsta, SiteGround, and WP Engine side by side.
Real-World Performance — What Testing Actually Shows
Most migration plugin comparisons are based on feature lists, not actual testing. The most rigorous independent test available — conducted by TeamUpdraft in 2024 — ran 8 plugins through 7 distinct stress scenarios with documented methodology.
Note: TeamUpdraft is the company behind UpdraftPlus, so their methodology should be read with that context in mind. That said, their results align with community reports and are the most detailed publicly available test data on this topic.
| Test Scenario | Best Performers | Failed or Struggled |
|---|---|---|
| Storage-constrained (99% disk full) | Migrate Guru, UpdraftPlus, BlogVault, InstaWP | Duplicator, All-in-One, WP Migrate, BoldGrid |
| Connection cut-out recovery | UpdraftPlus, BlogVault, Migrate Guru | All others (migration failed or required restart) |
| Low memory source (128MB RAM) | UpdraftPlus, All-in-One, BoldGrid (~1min 40s) | Duplicator (partial failure on mu-plugin files) |
| Large database (300MB) | UpdraftPlus, BoldGrid (under 2 min) | InstaWP (14 min 18 sec — slowest) |
| File-heavy sites (500MB+ media) | UpdraftPlus, BoldGrid (under 2 min) | WP Migrate (database only, files failed) |
| WordPress multisite migration | All-in-One, UpdraftPlus, Duplicator | Migrate Guru, InstaWP, BoldGrid, WP Migrate |
Key takeaway: UpdraftPlus was the most consistent performer across all scenarios. Migrate Guru excelled in storage-constrained and connection recovery scenarios. WP Migrate — despite its developer reputation — failed to migrate media and plugin files in the file-heavy test. For multisite, only three plugins passed: All-in-One WP Migration, UpdraftPlus, and Duplicator.
What Is Serialized Data (And Why It Can Break Your Migration)
WordPress stores most of its settings in the database as plain text. But for complex data — like a widget configuration containing an array of settings, or a theme that stores its options as an object — PHP serialization is used. The result looks something like:
a:2:{s:5:"title";s:12:"Hello World!";s:7:"enabled";b:1;}
The number at the start of each string segment tells PHP exactly how many characters to expect. If you run a simple find-and-replace on the SQL file — say, swapping http://oldsite.com for http://newsite.com — the character count changes. PHP then fails to unserialize the data, and the setting is silently lost or displays as an empty string.
Good migration plugins detect serialized data and run a special find-and-replace that recalculates character counts correctly. This is not optional — it’s a baseline requirement. Every plugin covered in this article handles it. If you’re evaluating a plugin not on this list, verify this explicitly before using it.

Who Should Use Which Plugin — Decision Guide
The honest answer to “which migration plugin is best” is: it depends on your specific situation. This table cuts through the noise.
| Your Situation | Best Plugin |
|---|---|
| One-time move, beginner, site under 512MB, not on Kinsta | All-in-One WP Migration (free) |
| One-time move, free, site over 512MB, shared hosting | Migrate Guru (free, server-side) |
| One-time move, need both backup and migration, any size | UpdraftPlus (free version now supports both) |
| Full-featured, guided migration, budget allows | Duplicator Pro |
| Developer, frequent DB moves, local-to-staging-to-production | WP Migrate Pro |
| Agency, complex multisite, strict SLA requirements | Solid Backups or Duplicator Pro |
| Moving TO SiteGround specifically | SiteGround Migrator (free, token-based) |
| On Kinsta (avoid All-in-One) | Duplicator, Migrate Guru, UpdraftPlus, or WP Migrate |
| Moving a large WooCommerce store (large DB + media) | Migrate Guru (server-side) or UpdraftPlus Premium |
| Migrating WordPress multisite network | Duplicator Pro or All-in-One WP Migration (with Multisite Extension) |

Frequently Asked Questions
Is there a completely free WordPress migration plugin?
Yes — Migrate Guru is completely free with no paid tier at all. It handles sites up to 200 GB using server-side migration (runs on BlogVault’s servers), so it doesn’t load your source hosting. The only limits are 5 migrations per user per month, and it doesn’t support localhost environments. UpdraftPlus also includes basic migration in its free version since August 2023.
What is the file size limit for the free version of All-in-One WP Migration?
The free version of All-in-One WP Migration caps import file size at 512MB. If your site export file exceeds that, the import will fail. You have two options: purchase the Unlimited Extension (from $69) which removes the size restriction, or switch to a plugin without this limitation — Migrate Guru (free, server-side) or Duplicator work well for larger sites.
Can Migrate Guru be used to back up my WordPress site?
No. Migrate Guru is a migration-only tool — it moves your site from one location to another but does not create or store backups. If you need both migration and backup in one plugin, use UpdraftPlus (free version covers both) or Duplicator Pro. Always have a backup before migrating, even if it’s a separate tool.
Which WordPress migration plugins work on Kinsta?
Kinsta bans All-in-One WP Migration on production servers because it causes disk I/O instability. The plugins that work well on Kinsta include Duplicator, Migrate Guru, UpdraftPlus, and WP Migrate. Kinsta also offers its own free migration service through its dashboard for incoming migrations.
What is the difference between a WordPress migration and a backup?
A migration moves your site from one host or domain to another. A backup creates a stored copy you can restore from if something goes wrong. They serve different purposes. Some plugins (UpdraftPlus, Duplicator, Solid Backups) handle both. Migrate Guru is migration-only. Using a migration plugin without first creating a backup is a risk — if the migration fails, you may not have a clean restore point.
How do I fix 404 errors on all pages after migrating my WordPress site?
This is the most common post-migration issue and the fix is simple: go to Settings > Permalinks in your WordPress dashboard and click Save Changes. This forces WordPress to regenerate your .htaccess rewrite rules on the new server. If that doesn’t work, check that your .htaccess file was transferred correctly and that your new host has mod_rewrite enabled (for Apache) or the equivalent Nginx rules configured.
Can I migrate a WordPress multisite network with a plugin?
Yes, but not with every plugin. In real-world testing, only three plugins successfully handled full WordPress multisite network migrations: All-in-One WP Migration (with the Multisite Extension, from $319), UpdraftPlus, and Duplicator Pro. Migrate Guru does not support multisite subsite-to-different-domain migrations. WP Migrate and most other plugins also failed or do not support this use case.
Will migrating my WordPress site to a new host affect my SEO rankings?
If you’re moving to a new host but keeping the same domain, and the migration is done correctly, your SEO rankings should remain intact. The plugin preserves all your content, URLs, and metadata. If you’re changing domains, you’ll need 301 redirects from every old URL to its new equivalent, and Google’s Search Console “Change of Address” tool. Expect a temporary fluctuation of 10-20% in rankings for 1-2 weeks after a domain migration, which typically normalizes. Keep your old host and redirects active for at least 12 months.
Conclusion
For most WordPress users doing a straightforward host migration, the choice comes down to two factors: site size and budget. Migrate Guru covers large sites for free. All-in-One WP Migration works for smaller sites and offers the simplest interface. Duplicator Pro is the best all-around paid option.
For ongoing migrations — moving between environments, syncing databases during development — WP Migrate Pro is built exactly for that workflow and has no real competition in that niche.
The host compatibility issue deserves more attention than it gets. If you’re on Kinsta, Migrate Guru or Duplicator are the safe choices. If you’re moving to SiteGround, their own free plugin is the path of least resistance. Checking this before you start a migration saves real time.
Performance data from real-world testing supports UpdraftPlus as the most resilient option under difficult conditions — connection drops, storage constraints, memory limits. For anyone who runs into those scenarios regularly, that matters more than feature lists.
