[Dovecot] 1.1 -> 1.2 upgrade?

[Dave McGuire]

   Hey folks.  I'm currently running Dovecot v1.1.6, and would like  
to move to 1.2.x soon.  I'm using MySQL-backed LDA and fully  
virtualized mailboxes.  Are there any upgrade gotchas I should be  
aware of?  How much config file hacking should I expect?

             Thanks,
             -Dave
