Frequently Asked Questions

Common questions about Open Migration - Unlimited Site Transfer & Backup

The archive is sliced into small pieces in the browser and reassembled on the server, so your host's upload_max_filesize and post_max_size limits do not apply. The chunk size is chosen automatically from your server's own limits.

No. The conversion runs automatically as part of the import and reports how many database rows it changed.

Restoring the database replaces the destination's user accounts with the ones from the archive, which invalidates your current session. Log back in with the username and password from the original site. If your account exists on both sites with administrator rights, the plugin signs you back in automatically.

Nothing changes by itself - the database still contains the temporary address, so WordPress redirects visitors back to it. Once the real domain loads the new server, open the Change Domain tab, enter the real address and run it. That rewrites everything in one pass, including serialised and JSON-escaped references.

Yes. The Change Domain tab works at any time and is not tied to an import.

Yes. The prefix is recorded in the archive and converted during the restore, including the prefixed keys inside options and usermeta.

Not yet. Multisite networks are detected and refused rather than partially migrated.

PHP 7.2 or newer with the ZipArchive extension enabled, and enough free disk space for the archive. The Export tab shows a server check before you start.

In wp-content/uploads/open-migration-unlimited-site-transfer-backup/. That directory is protected with deny-all rules for Apache and IIS, carries an index file, and archive names include 32 random characters. Downloads are streamed through WordPress only after a capability and nonce check, so the folder never has to be publicly readable - which also keeps it safe on Nginx, where .htaccess files are ignored.

Only when you use the Site-to-Site tab, and only to the address you supply. Generating a token makes one request to your own site's REST API to confirm it is reachable. Pulling a site makes a request to the source site whose token you pasted. No data is sent to the plugin author or any third party, and no analytics or tracking of any kind is included.
