I'd review the configfiles and especially the great update documentation
from timo. For now we look save.

As far as I remember we just adjusted the mailbox path (mail_location)
and protocols (imaps/pop3s). And we use ssl certificates.

No mysql, sieve or quota etc stuff.

That's the point :) currently I don't have the hardware and time to
install a new system. So we thought doing a minor upgrade will improve
things a bit and we can get rid of one old bug without getting to much
trouble by doing a very big step ahead.

I read something about the index and mailbox/mailstorage formats might
have changed a bit and that dovecot is converting/correcting tham on the
flight.

Did you notice something like that?

What do you mean by that? BTW it's strange to me that Redhat never
updated the main imap server part in there lon tearm supported
enterprice distribution ... (RH EL 6 comes with dovecot 2.0 ok ... )
