I have moved my installation a couple of times. It's not difficult.
What I did was this:
- Create a new installation of Courier on the new server
- Copy over the config files from the old server
- Make any config changes needed (server name, IP, etc)
- Rsync maildirs from the old server (while it's still running)
- Shutdown Courier on the old server
- Rsync the maildirs again to pick up any last minute changes
- Bring up the new server
The only downtime will be during the second rsync, which will not take
nearly as long as the first one. Don't forget the authlib config files.
The only thing this doesn't get you is the contents of the outgoing
mailq. I don't think there is a good way to transfer that to the new
server. What I did was just let the old server run with no incoming
smtp or pop3 access for a day or so to let the queue clear out as much
as possible before I shut it down completely.
