Yeah but that will copy the full database which AFAIK is not the idea. (not sure tho, I'm been messing with ispconfig for a few weeks only)
so when it first happened to me I took the conservative approach of copying the mail_user server mail_forwarding (And a few others that I cant remember) but only where server_id = the server_id of the server I was trying to reconstruct.
After that I just started making a daily dump and a pre update dump (which I believe is now part of the standard update or I just missed that it was already part of it)
Anyway it just works now which is always a good thing
