Hi there @brightbluegum,
All of the data associated with the Jetpack connection is connected to the site’s domain, rather than to a specific WordPress.com account. So there’s no need for your client to reconnect Jetpack using the same WordPress.com account as before. They can reconnect using whichever account is convenient for them.
The only time you’d want to be sure to reconnect it to the same WordPress.com account is if there were paid Jetpack subscriptions involved, but it looks like this particular site doesn’t have any paid subscriptions, so that’s not an issue here. Hope that helps!
A side note: Jetpack communicates with your site using XML-RPC, and it looks like there are some XML-RPC issues on this site, so if the client is hoping to use Jetpack, you’ll want to resolve those issues.
You can see an example of a working XML-RPC file here:
https://wp.cloud/xmlrpc.php
It should show XML-RPC server accepts POST requests only. If you visit your site’s xmlrpc.php file by appending /xmlrpc.php after the domain, you’ll see it is loading with a server error. You may need to check with your web host to see what is going on there.
Please let us know if we can help with anything else.
