If you do not change the logic of the config, keep the same mail storage 
format, etc.pp., Dovecot should update all Dovecot-related files and it 
should work. However, you cannot go back without loosing some information 
depending on your storage.

Therefore, it is always wise to: backup everything and do a test on a test 
system before touching the production server.
