A green transfer result is useful, but it is not the end of a WordPress media migration. The important question is whether the files people actually request still work.
I build tools at LumoWP. Here is the handover checklist I would use around our Lumo FTP Media plugin. These are validation steps, not a claim that every theme and host has been certified.
1. Check the public URL without a session
Open a transferred image in a private or signed-out browser. It should be accessible through the intended HTTPS address without a storage login. Check the response and the image itself; a login page can return a successful HTTP response too.
2. Test more than the original
WordPress can create multiple image sizes. A product card may use a different file from the product gallery. Test both. If the full-size image works but the card is broken, inspect the actual requested thumbnail rather than retransferring the whole library blindly.
3. Include mobile and page-builder content
A desktop screenshot is not enough. Review mobile galleries, responsive image selection and any Elementor backgrounds or widgets that use media. Confirm the intended delivery hostname is being used.
4. Keep rollback practical
Retain backups and local copies during validation. Record the settings you changed and confirm how to return to the previous delivery setup. Remote storage is not automatically a backup, especially if deletions or credentials affect both environments.
5. Measure what changed
Storage capacity, transfer reliability and loading speed are separate outcomes. Compare equivalent pages under similar conditions. Avoid turning a storage change into an unsupported SEO promise.
How Lumo FTP Media helps
Our WordPress FTP media plugin handles transfers and media URL rewriting. Automatic-upload rules and existing-media sync help apply the same workflow to future uploads and older files.
The useful order is: configure, pilot, verify real pages, expand, then review local retention. Image dimensions, compression and meaningful alt text still need their own attention.
If you are planning a migration, our media offload guide explains the relationship between storage, delivery and image SEO.
Which additional check would you include before handing the site back to a client?
