Yup. Easy upgrading is a must.

If possible it may be nicer to enter a "read-only" mode where no changes
were permitted (to data or file) but the application would continue with
a warning to the user about the current state of play. Not sure how easy
this would be to implement so it's maybe not worth the hassle!

Still it would perhaps be nicer for the user should they find themselves
in that situation (I'm thinking ahead to when NFS mounted shares are OK
and users could conceivably login with different DK versions relatively
easily).
