So you currently have 2.3.9 and want to upgrade to 2.3.11? I found the following: > > file /usr/local/etc/sasldb2: > /usr/local/etc/sasldb2.db: Berkeley DB 1.85 (Hash, version 2, native byte-order) > > -> Do I need to upgrade the sasldb2 or can I let is as is? sasldb2 is not directly used by cyrus-imapd, it is used by cyrus-sasl2. If your upgrade doesn't involve upgrading cyrus-sasl2 then you don't need to worry about sasldb2. > > file /var/imap/*.db: > - annotations.db: Apple QuickTime movie (modified)\012- Cyrus skiplist DB > > - deliver.db: Hitachi SH big-endian COFF object, not > stripped\012- Berkeley DB (Btree, version 8, native byte-order)\012- > Berkeley DB (Btree, version 8, little-endian) > > - mailboxes.db: Apple QuickTime movie (modified)\012- Cyrus skiplist DB > > - tls_sessions.db: Berkeley DB (Btree, version 8, native > byte-order)\012- Berkeley DB (Btree, version 8, little-endian) > > pkg_info|grep db: > db3-3.3.11_3,1 The Berkeley DB package, revision 3.3 > db41-4.1.25_4 The Berkeley DB package, revision 4.1 Danger Will Robinson! Having multiple versions of BDB on the same machine is an easy way to shoot yourself in the foot during installation of any BDB-dependent software.. > db3_dump deliver.db and tls_sessions.db: > VERSION=3 > format=bytevalue > type=btree > ... > This means for me it's db3.

You could also just leave these files in db3 format by specifying WITH_BDB_VER=3 during the port build. tls_sessions.db is a transient file anyway and if you just delete it then Cyrus re-creates it. It is used to keep track of current TLS sessions, as it's name implies. In my experience, deliver.db is also automatically re-created by Cyrus so it can be deleted, but I'm not sure what you lose if you do so. I have migrated Cyrus to another server 3 times during past couple of years and I've never bothered to transfer deliver.db from old server to new.

Did I foreget > something? /var/imap/db is the 'Berkeley DB environment', whatever that means. If you do decide to go from db3 to db4 then you probably need to do something about it. /var/imap/user is important. It contains files that keep track about which users have subscribed to which mailboxes and which messages they have read. It survives 2.3.9 -> 2.3.11 upgrade without any problems.
