I'm planning an upgrade from a Cyrus-2.2.8 to Cyrus-2.2.12. However, we

performance issues with the first.
So now I'm wondering: should I call db_upgrade from Berkeley on each of
these databases? And which databases exactly would that be? This is a
stock standard 2.2.8, with no specific backends mentioned in the
imapd.conf or compiled in. What are the filenames/locations where I
should find Berkeley db files?
If it where me I would downgrade your bdb back to 4.1.25 so that you can
read the files then export them to text format. Once you upgrade cyrus,
import them into skiplist format and be done with bdb.
I have a fairly large system and was always bumping into bdb problems so
about a week ago I finally decided to go to skiplist format and haven't
looked back.
Skiplist should also make things easier next time you upgrade since it
doesn't depend on external libraries and their versions.
Thank you for your reply. I was already considering changing to
skiplist, but at the moment the problem is that I don't know which
database is where, and what kind of backend it is. On my test-machine, I
think I've located all Berkeley's, but Cyrus is completely dead, failing
with a 'DB4' error. So first of all I'm trying to find which ones I'm
missing - which is getting a bit urgent, given the planned upgrade for
tomorrow :-/
