Could you please give me a hint what you mean with configdirectory?
In my case (SuSE 10.0 as well as 9.2) I found a subdirectory db 
in /var/lib/imap the directory where the database seems to be located.
There is a directory deliverdb with a subdirectory db in the same place.
As having copied the whole directory /var/lib/imap including subdirectories  
from the old installation to the new one I cant´t imagine that these old 
directories are the cause of a changed Berkeley DB version.
