Can you please ellaborate why I should make sure that all these certificates know about the new host name? If this was a plain ssh key it would just work by copying and pasting its private key file. That's why my doubts. I don't mind if https at the browser complains about having one certificate for one domain and being another one.

I'll check that later. I understand that if no difference is found apart from the database password then no need to modify it in the destination. Thank you! -- -- Adrián Gibanel I.T.
