I don't know about the Debian packages but as a maintainer of RPM packages, I implemented some db converting mechanisms which will automagically convert any dbs on the fly. I have used my own packages on different servers and haven't had any problems. The good thing is that I also didn't get any problem reports concerning the db conversion. Would be nice to get some feedback from people who are using my rpms.
