Probably a lot running 1.1 still.  I only upgraded late last year because
I needed additional functionality (see below), otherwise I'd still be
on 1.1 now.

Yes, and it was painless.  All the info you need is on the dovecot wiki.

No.

We ran solely mbox with 1.1.  The reason I upgrade to 1.2 was to be
able to run primarily mbox, but also run a few maildir accounts for
shared folders with per-user flags with easy time-based expiration (retention
policy).  So we just have a couple maildir accounts used exclusively as
shared-folder accounts (with per-user-flags and auto-expiration of messages
after a set rention period) and the rest are still mbox ( with no
retention/expiration, no shared folders, etc)

If it wasn't for the desire to do the shared folders with expiration, we'd
have stayed with 1.1 still.

It was a painless process for me.  No problems.

We uprgaded on CentOS 5.x using RPM packages from atrpms.net, and going
from dovecot-1.1.18-1_95.el5.x86_64.rpm to dovecot-1.2.4-0_99.el5.x86_64.rpm
if that's any help. :)
