We did a migration some months back from an old Kolab v1 (cyrus v2.1)
system to a new Kolab v2.2 (cyrus v2.2) system.
This was done by writing a script to
- dump the ldap database (you might not have this) and load it on the new
- rsync the mailboxes from their location on the old server to the
correct location on the new server
- recursively reconstruct those mailboxes
- copy the .seen and .sub information to the correct new location
- copy the quota information to the correct new location
- dump the old mailboxes.db and load it on the new system (with cyrus
It's not trivial, but it can be done with some care. We also had to
translate usernames from <user> to <user>@<domain> in various places to
match the new kolab setup but you probably won't have to worry about that.
