All-in-One WP Migration Review: Best Free Migration Plugin? (2026)

What Is All-in-One WP Migration?

All-in-One WP Migration is a WordPress plugin by ServMask that lets you export your entire website — database, media, themes, plugins, and all — into a single .wpress file. You then import that file on your new host. No FTP, no database exports, no command line. It has over 5 million active installs and a 4.6/5 star rating on WordPress.org.

Key Features

• One-click export — Creates a single .wpress file containing your complete site
• Drag-and-drop import — Upload the file on your new host and the plugin handles everything
• Automatic URL replacement — Updates all internal links, serialized data, and database references to match your new domain
• No technical knowledge needed — No FTP, no MySQL database exports, no command line
• Cloud storage extensions — Export directly to Google Drive, Dropbox, Amazon S3, and 14+ other cloud providers (paid)
• Works with any host — Compatible with all WordPress hosting providers
• Built-in backup — The export file doubles as a full site backup

Free vs Premium

This is where it gets tricky. The free version works, but has a 512 MB import limit. Most WordPress sites with images exceed this quickly. Your options:

• Free version — Export unlimited, import up to 512 MB. Fine for small sites or test environments.
• Unlimited Extension — $69/year. Removes the import size limit entirely. This is what most people end up buying.
• Cloud extensions — $99/year each. Google Drive, Dropbox, S3, etc. Export directly to cloud storage.
• Premium bundle — All extensions combined for a higher price.

The free version is essentially a demo for sites under 512 MB. For real migrations, you will almost certainly need the $69 Unlimited Extension.

Pros and Cons

Pros:

• The simplest migration workflow available — truly one-click
• Handles serialized data and URL replacement automatically
• Works across any hosting environment
• Export files serve as complete backups
• Massive user base means excellent community support

Cons:

• 512 MB free import limit is restrictive — most real sites need the paid extension
• Cloud storage requires separate paid extensions ($99/year each)
• Large sites can produce multi-GB export files that are slow to transfer
• No incremental backups — full export every time
• The "free" marketing feels misleading given the import limit

Who Should Use It?

All-in-One WP Migration is ideal if you need to migrate a WordPress site to a new host and want the absolute simplest process. It is especially good for non-technical users who do not want to deal with FTP, database exports, or WP-CLI. If your site is under 512 MB, the free version is genuinely useful. For larger sites, the $69/year Unlimited Extension is the real product.

Best Alternatives

• UpdraftPlus — Free backups with scheduled automation and cloud storage. Better for ongoing backups, but migration requires the paid Migrator addon ($30).
• Duplicator — Free migration plugin with no import size limit on the free version. More technical but more generous. Great alternative if you do not want to pay $69.
• Your hosting provider — Many hosts (SiteGround, Kinsta, WP Engine) offer free site migration as part of their hosting plans.

Frequently Asked Questions

Is All-in-One WP Migration really free?

The export is free with no limits. The import is free up to 512 MB. Most WordPress sites with images exceed this, so you will likely need the $69/year Unlimited Extension for real migrations.

How long does a migration take?

It depends on your site size and server speed. A small blog (under 500 MB) typically takes 5-10 minutes total. A large WooCommerce site (several GB) can take 30-60 minutes.

Will my SEO rankings be affected by migrating?

Not if done correctly. The plugin updates all internal URLs automatically. Make sure your permalink structure stays the same and set up 301 redirects if your domain changes.

Can I migrate to a different domain name?

Yes. The plugin automatically finds and replaces all references to your old domain with the new one during import, including serialized data in the database.

Is there a file size limit for exports?

No. You can export sites of any size for free. The limit only applies to imports (512 MB on free, unlimited on paid).
