Ensure users cannot migrate a site into itself

[sixhours]

We discussed this already via email but I wanted to create an issue to have a centralized place to track it.

It would be ideal if users could not migrate a site to itself. We'd like to add some kind of validation to prevent this from happening.

Hi @sixhours , We've implemented a fix to address this. If users attempt to migrate a site to itself, they’ll receive a clear error message to prevent the action. This update should be deployed within the next few days.
