migrate mailboxes from cyrus-imap-1.6.24 to cyrus-imapd-2.3.7

[Alexander Tsebenko]

Hello

We need to migrate lots of |cyrus mailboxes| from one host 
(cyrus-imap-1.6.24_4 with cyrus-sasl-1.5.28_3)
to new host (cyrus-imapd-2.3.7 with cyrus-sasl-2.1.22 ).
Authentication is done via mysql plugin. MySQL user base on third machine
I've tested that new cyrus authenticate test user just fine.

May we just rsync user folders to complete migration?
