Hi, I'm looking to migrate an existing courier-imap installation from one server to another. My concern is that if I get something wrong, it may not be apparent until rather late in the process and there's a risk of data loss. I can't seem to find anything in Google which suggests I might hit a problem, however I'd like to get a second opinion from the list before I go charging in.
Current scenario: 1 x Gentoo server. Emails are received through sendmail, processed through procmail and picked up by users using courier-imap. The mail storage is in maildirs - some 60GB of them - all rooted in /home/<USERNAME>/.maildir. Desired scenario: 1 x Debian Etch server I'm not sure what I'll end up using as the MTA (but it must support Sendmail-style aliases files, and I've got Postfix in a number of places so that's a strong possibility), processed through procmail and picked up using courier-imap. Maildirs will remain housed in /home/<USERNAME>/.maildir There will be no hardware similarities between the two servers, and very few configuration similarities. They will have different hostnames, IP addresses. My plan is to shutdown courier-imap and rsync -a the maildirs from the source to the destination server. Once complete, I'll CNAME the old IMAP hostname to the new one, users will connect to the new IMAP server. With any luck, I'm hoping that the end result will be a transparent migration. Have I got the right idea?
