I am new to Berkeley DB and have a question if anyone can help.

Is it possible to create DB files on v4.4.20 (with AES Encryption) and
then recover/import those files into Berkeley DB v4.1.25? The website
says there is a logfile change, will this affect the import?

Any input would be appreciated. Thanks.

This depends on what, exactly, you are trying to do. You can create
databases
in v4.4.20 and access those in v4.1.25. There have not been database
format
changes between those versions. The log format has changed and you
cannot
use a 4.4.20 log and expect 4.1.25 to understand it.

If you want to import that database into a 4.1.25 transactional
environment so that
it can be recovered, etc, then you will need to dump and reload the
database.
You can do that by using db_dump in 4.4.20 (with -P since it is
encrypted). Note
that the output produced by db_dump will be in the clear.
Then you use db_load in 4.1.25 (with or without -P depending on if you
want
encryption on that side) specifying your 4.1.25 transactional
environment home directory.
