Hi, I've inherited a postfix/dovecot/postfixadmin/squirrelmail setup.
I'm looking to cut over from the live mail server to this other server. I'm trying to figure out how to do this cut-over properly. I've installed and configured postfix/dovecot/postfixadmin/squirrelmail as best I could and with the same setup as the live server. I also want to use the same mx dns record. Here's what I'm not sure: - When would I copy the virtual mailboxes from the live server to the other server? Would I do this after switching the DNS MX record? What would be the proper sequence? The following? - Edit DNS MX record. - Copy mailboxes to other server. - Test other server I realize this is generalized without much detail. I have never done this before so I just want to make sure I do this without losing any mail. Downtime is not an issue as long as it is not more than an hour or 2. Thanks, Charles
