Choose Duplicator if you prefer an archive-and-installer process or need paid options such as multisite support, staging, or scheduled and remote backups. Site size and hosting limits matter, and neither plugin is proven universally faster or more reliable by the available comparative evidence.
How the two migration workflows differ
All-in-One WP Migration: export one file, then import it
All-in-One WP Migration and Backup, published by ServMask, packages a WordPress site’s database, media, themes, and plugins into a single .wpress file. The vendor’s WordPress.org listing says its importer updates URL references and handles serialized data, which can otherwise be damaged by simplistic search-and-replace operations.
The usual pattern is to export from the source site, install WordPress and the plugin at the destination, then import the .wpress file. The plugin’s listing recommends clearing caches and resaving permalinks after restoring. Keep in mind that an import overwrites the destination site’s content and database; use a clean destination or make a separate copy before proceeding.
Duplicator: transfer an archive and installer
Duplicator’s classic workflow creates a site archive and an installer.php file. You transfer both to the destination, run the installer, and follow its steps to extract files, restore the database, and replace old URLs. Duplicator documents this process in its plugin workflow guide. Duplicator Pro also offers recovery points and a newer import workflow, so the classic installer is not the only option for paid users.
Recommended Free Tools
The installer approach gives you a distinct setup step outside the normal WordPress import screen. Follow the installer’s prompts and review its reports rather than assuming a completed archive means the destination is working correctly.
Which is a better fit for your site?
| Situation | Likely fit | What to check |
|---|---|---|
| A straightforward migration of one site, with a dashboard-based import | All-in-One WP Migration | Confirm the destination host can upload and import the resulting .wpress file. The official listing reviewed does not establish a current free import cap. |
| You want an archive plus a separate installer step | Duplicator | Make sure the destination host can build or unpack the selected archive format and run the installer. |
| A large site or hosting with limited PHP resources | Depends on site and host; test before choosing | Duplicator’s free DupArchive engine is documented for sites up to 500 MB. ZIP capacity varies with PHP architecture and host resources, and a host can stop an archive build early. |
| A multisite network or subsite migration | Check the exact plan and operation; Duplicator Pro is a documented option | Duplicator’s free plugin does not support multisite. Its Pro listing includes multisite network support and subsite migration options. All-in-One’s listing notes network-level multisite capabilities, but verify the tier and operation you need. |
| Scheduled backups or remote storage | Compare the required plan features | All-in-One documents local downloads and cloud storage; Duplicator lists local folders and Duplicator Cloud, with Pro integrations including Dropbox, Google Drive, OneDrive, Amazon S3, and FTP/SFTP. |
Understand size limits and hosting constraints
Do not treat a plugin’s archive limit as a guarantee that a migration will work on every host. Duplicator documents its free DupArchive engine for sites up to 500 MB; that figure applies to that engine, not every archive format or host. ZIP capacity depends on 32-bit or 64-bit PHP and the available host resources. A host may terminate a build before it finishes. See Duplicator’s workflow documentation for its engine and resource guidance.
For All-in-One WP Migration, the official listing reviewed describes the single-file export and import but does not establish a current free import limit. Avoid relying on a number from an older comparison page: check ServMask’s current documentation and test with the actual destination’s upload, execution-time, and storage constraints.
Compare backup destinations and restore options
All-in-One’s documentation describes exporting a local file and using cloud storage, and its listing refers to support for major cloud services. Duplicator describes local folders and Duplicator Cloud; its Pro integrations include Dropbox, Google Drive, OneDrive, Amazon S3, and FTP/SFTP. Verify that the destination you need is available in the specific edition you plan to use.
Rank #3
A migration package is not a proven backup until you have restored it successfully. Test the chosen workflow on staging, and keep an independent off-site copy. A local download can be useful, but it does not protect against loss of the computer or storage device holding it.
Check plan features and renewal costs before paying
Duplicator’s vendor pricing page lists Basic, Plus, Pro, and Elite plans with different site counts and features. It lists Pro at a regular price of $399, in USD, and states that introductory discounts do not apply to renewals. These are the page’s terms as checked on September 30, 2026; confirm current pricing and renewal details on Duplicator’s pricing page before purchase.
The current All-in-One paid tier boundaries and prices were not established in the official material reviewed. Check ServMask’s current extension and license pages for the exact combination of multisite support, storage, and other features you need rather than assuming a feature is included in a particular tier.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A practical way to decide
- Identify the job: a single-site move, a recurring backup, a multisite operation, or a recovery workflow may call for different features.
- Check the destination host: confirm upload limits, PHP architecture and resources, and whether you can run the required import or installer process.
- Match the plan to the task: verify multisite, staging, scheduling, and remote-storage support in the exact edition before paying.
- Run a test restore: use staging where possible, check the resulting site, and keep the source host available as a rollback option. All-in-One’s listing suggests keeping the old host active for 7–14 days; that is vendor guidance, not a universal requirement.
No matched independent benchmark establishes that either plugin is faster, safer, or more reliable overall. Pick the workflow and plan that satisfy your site’s requirements, then validate the restored site yourself.
