Planning a cyrus upgrade

[Paul Boven]

L.S.,

I've been running cyrus imapd version 2.1.10 with cyrus-sasl-2.1.9 for a
while, and apart
of some glitches with Berkely-dB 4.1.25, am quite pleased with it. From
this mailinglist I
understand that the Berkeley-dB bug has been solved, so that sounds like
a good reason
to upgrade. Is this particular bug-fix already in a stable release? I'm
planning to upgrade
to 2.1.12, given the 'alpha' status of the 2.2 branch.

Secondly, most of my mail-users use Mozilla or Outlook. Both open
multiple connections,
and because of this, mail you've already read tends to become unread
again. I've heard about
a patch to make cyrus write these changes to disk right away to keep
them synchronized
between connections. Where to find such a patch? Is it already part of
the cyrus tree?

 From the documentation, I understand that (I won't change Berkely-dB
versions) upgrading
from this version of Cyrus to a more recent one shouldn't be a problem,
just stop the server, replace the binaries, and start it again. Is this
enough of a plan, apart from making a full backup first?

Regards, Paul Boven.
