The free All-in-One WP Migration plugin skips multisite entirely — try to export a network with it and you get a polite refusal. The Multisite Extension is the official fix: it adds full network export and import to All-in-One WP Migration, including the choice between the whole network and a single sub-site. If you maintain client networks or staging copies of a multisite install, this is the tool that makes the job a two-click operation.
What makes it genuinely useful is the selective mode. You can pull one sub-site out of a network and import it as a standalone site, or take a standalone site and graft it into an existing network. That covers the two migrations people actually need — breaking a site out of a network, and moving a site into one — and neither is trivial to do by hand because of how multisite stores site-specific paths in the database. Combine it with the Unlimited Extension to remove size caps, and a Duplicator Pro comparison comes down to how often you do network-level work.
Competitive Features
- Full network export and import — captures every site in the network, plus users with their network roles, in a single
.wpressarchive - Sub-site extraction — exports one sub-site with its content, media, and settings, ready to import as a standalone WordPress install
- Standalone-to-network import — pulls a standalone site into a network as a new sub-site, rewriting paths and tables correctly
- URL and path rewriting — handles the
wp_blogsand site-table rewrites that make manual multisite moves error-prone - Drag-and-drop restore — the same simple importer as the base plugin, so restoring a network does not require SSH or database surgery
- No configuration overhead — activate, pick the export scope, done; there is no settings maze to learn
- Works with the extension family — combine with storage extensions like Google Drive for off-server network backups
Key Features
- Selective export scope — the export screen offers “Entire network” and individual site selection, each producing a compatible archive for its target scenario
- User handling — network users and their per-site roles export and import with the archive, so permissions survive the move
- Media library integrity — uploads are organized per sub-site (
blogs.dirstructure) and reassembled correctly on import, which is where most DIY migrations break - Overwrite filters — choose whether the import replaces plugins, themes, and media or leaves the destination versions untouched
- Chunked import engine — large networks import in PHP-managed chunks, avoiding timeout limits on shared hosting
- Domain mapping awareness — handles mapped domains where configured, reducing post-import fixups on production networks
- GPL license — unlimited use across client projects, including staging and production networks
Comparison with Competitors
All-in-One WP Migration Multisite vs Duplicator Pro
| Feature | All-in-One WP Migration Multisite | Duplicator Pro |
|---|---|---|
| Network export | Yes, with sub-site selection | Yes, full network |
| Sub-site to standalone | Yes, built-in | Manual configuration |
| Scheduled network backups | No | Yes |
| Cloud storage | Via extensions | Built-in |
| Learning curve | Minimal | Moderate |
| Best for | Targeted multisite moves | Full backup routines |
Duplicator Pro is the better scheduled-backup tool. For the specific jobs of extracting or grafting sub-sites, the Multisite Extension is more direct — Duplicator requires package wizardry for the same result.
All-in-One WP Migration Multisite vs WPvivid Backup Pro
| Feature | All-in-One WP Migration Multisite | WPvivid Backup Pro |
|---|---|---|
| Primary use | Multisite migration | Backup and migration |
| Sub-site extraction | One-click | Limited |
| Import interface | Drag-and-drop | File upload screens |
| Staging | No | Yes |
| Best for | Network restructuring | Recurring protection |
WPvivid covers general backup duties well, but sub-site extraction is the Multisite Extension’s specialty and it does it with fewer steps.
Recommended Stack — use the Multisite Extension for network restructuring and pair it with UpdraftPlus Premium for scheduled backups so every sub-site is protected between migrations. If import size limits get in your way on large networks, add the Unlimited Extension from the same developer.

Frequently Asked Questions
Do I need the free All-in-One WP Migration plugin installed?
Yes. The Multisite Extension is an add-on to the base plugin and does nothing on its own. Install the base plugin first, then activate this extension.
Can I export just one sub-site from a network?
Yes. The export screen lets you choose between the entire network and individual sub-sites. A sub-site export imports as a standalone site.
Can I move a standalone site into an existing multisite network?
Yes. Importing a standalone archive on a network installation creates a new sub-site, with database tables and upload paths rewritten for the network structure.
Does it migrate network users and roles?
Network-level exports include users and their per-site roles. Sub-site exports include users assigned to that specific site.
What about the import size limit on large networks?
The extension itself does not lift the base plugin’s size cap. For big networks, pair it with the Unlimited Extension, which removes the import limit entirely.
Is this compatible with WordPress’s current multisite architecture?
Yes. It handles the standard subdirectory and subdomain multisite configurations, including per-site upload directories, and is updated whenever WordPress core changes the underlying structure.
