That's good news ;-)

I expect I have to do this, when syncing the mailbox "paul":
- create a mailbox with the same name on the new server
- sync /var/spool/cyrus/mail/p/user/paul
- sync /var/lib/cyrus/user/p/paul/paul.*
- sync /var/spool/sieve/p/paul

Is that everything?
What when I have to change the name of the mailbox, because of a
duplicate name on the new server?

I am using skiplist, so I think I don't need that. Correct?
In this case I go from a 64-bit AMD system to a 32-bit Intel system.

No, it's still 2.2, but good to know for the future.

With regards,
Paul.
