And as mentioned on the cyrus-devel list:

Based on this information, and given that only a finite set of cyrus 
releases have likely been packaged for debian, it seems like it should 
be possible to determine which set of database files were generated for 
any possible debian installation.  Since all the debian cyrus db files 
are always in /var/lib/cyrus, it would seem that the postinst upgrade 
script can be simpler even than the one that redhat uses.
