I have an old Citadel server that I want to move mail from, the destination being a new Citadel server. The old server is older than the new over-the-wire or XML support, so I’m doing it the hard way and copying messages from one to another over the network. I found imapcopy.pl which is getting the job done nicely. Everything else will have to come over manually, which will actualy be faster thatn trying to upgrade anything. :/
A few observations:
- Clean out big mailboxes. My Sent Items folder had a ton of cruft that could be removed, and it made the process go a lot faster (no wai).
- Turn on IMAP protocol watching, otherwise you won’t know if something’s actually broke or not.
