>Description:
I rebuilt all my packages for NetBSD 3.0 using the latest version of
packages (no branch).
Switching from db4-4.3.29
to db4-4.4.16
results in failures in cyrus-imapd.

Is db 4.4 incompatible with 4.3-formatted databases?  If it's supposed
to be compatible, it's not and there's a bug somewhere.

If it's supposed to be incompatible, do we need to keep old & new
packages around (support multiple db4 releases)?

How about an upgrade/conversion guide?

>How-To-Repeat:
build cyrus-imapd & db4-4.3.29 on NetBSD-2.1, install them & use them
build cyrus-imapd & db4-4.4.16 on NetBSD-3.0.
upgrade the packages
restart cyrus
