I think that the key difference between using imapsync and upgrading cyrus is the amount of states that will be lost. I almost sure that with imapsync you cannot recreate: 1. Subscribed folders 2. Seen states for shared folders (also for INBOX if imapsync isn't used properly) 3. Shared seen states 4. Email flags (also for INBOX if imapsync isn't used properly) 5. Custom permissions Therefore I think that imapsync is not the best choice for corporate email servers or big installations.
