Hoping i'm not highjacking, my problem is somewhat same.

I would like to migrate users from one cyrus-imap to another cyrus-imap,
source having 'users\name' to destination having 'name at domain.tld'.

Just to make it interresting, i have one UW and one Cyrus server that has
to get merged into one Cyrus-imap.

I have been looking at imapsync, but i'm not shure about how to attack
this problem, having different sub-folders for the same user, on different
servers.

If any of you imap-gurus would like to share some insight, i'd really
appreciate to get enlightened.
