I'm working on replacing an old server running cyrus-imap 2.1.9 (on SuSE 8.1) with an install of CentOS 4.2 using the upstream provider's rebuilt rpm- which is cyrus-imapd-2.2.12-3.RHEL4.1. So far it is going well- I have the new server authenticating nicely from LDAP and a test mailbox which I can use.
I can see that the directory structure has changed - /var/spool/imap/user/tony has become /var/spool/imap/t/user/tony/ - and I read that the database formats have changed and will need rebuilding too.
Can anyone point me at any howto's for the easiest (or best) way to do a bulk migration like this?
I'm going to reply to myself since noone else was able to....
I figured out to use hashimapspool: false in imapd.conf to get the directory structure to stay as before.
I figure out after a while that SuSE had built 2.1.9 with skiplist already on, so I didn't need to convert the databases from berkeley to skiplist using cvt_cyrusdb.
I can now import my mailboxes and bring the server up - and it works apart from the .seen databases - so I'm getting pretty close.
If I do this on a sample mailbox's seen list:
/usr/lib/cyrus-imapd/cvt_cyrusdb /var/lib/imap/user/a/auser.seen flat /var/lib/imap/user/a/auser.seen.new skiplist
then I get the following in /var/log/maillog:
Feb 11 21:48:52 server cvt_cyrusdb[30400]: DBERROR db4: Program version 4.2 doesn't match environment version
Feb 11 21:48:52 server cvt_cyrusdb[30400]: DBERROR: dbenv->open '/var/lib/imap/db' failed: Invalid argument
Feb 11 21:48:52 server cvt_cyrusdb[30400]: DBERROR: init() on berkeley
which seems pretty odd to me.
Does anyone else recognise this error?
