I think with this sort of thing, you have to consider the likelyhood of
breakage.
If the nature of the application/configuration is relatively
straightforward, and/or compatibility between the two versions is very
strong, then I think the best thing to do is an automated migration.
If on the other hand, breakage is very likely, then probably "halt and
prompt" is best.
An intermediate possibility, might be if the app has very good
configuration file verification.
Then you could do the automigration, VERIFY it, and then halt noisily if
it fails verification.
A post thought: in this case, I think you should always only copy; never
remove. Worse case, 'mv' old config to config.migrated or something.
These points sounds like a good policy to me and are similar to what
I've talked about earlier.
