I have cyrus-imapd 2.3 with Berkeley DB 4.3 and openldap also compiled

Now, openldap won't build with 4.3 and defaults to 4.6 so I need to
migrate my data, and I would like to migrate my cyrus-imapd also to a
newer version of BDB.
Are there any tools or tricks for doing this?
The BDB v4.4 port refers to a compatibility page maintained at
sleepycat, but this is now redirected to Oracle and I find no such
information. Any page listing the db file compatibility?
Yes -- I believe BDB 4.3 and 4.6 aren't binary compatible it seems.
For the special case of cyrus-imapd you should use cvt_cyrusdb(8) to
dump out the contents of cyrus DB files to ascii, update everything, and
then use cvt_cyrusdb to reload the data.
Thanks, it doesn't seem that you can use this tool to convert from one
version of BDB to another:
Usage: /usr/local/cyrus/bin/cvt_cyrusdb [-C altconfig] <old db> <old db
backend> <new db> <new db backend>
Usable Backends: berkeley, berkeley-nosync, berkeley-hash,
berkeley-hash-nosync, flat, skiplist, quotalegacy
So, I can restructure but not upgrade... It doesn't seem like other
tools are provided with cyrus-imapd.
I took a look on the files in my imap-dir, and it's a mess. Maybe the
strategy would be to setup two servers and transfer mail one by one.
Anyone got experience with this?
