I don't see this as being much of an obstacle. I have migrated data
far more complex, and I venture to say that most of the rest of the
regular posters in this forum have too.

I suspect both are true, but in the unlikely event that we decide on
some massive change to the system, we can either run the DBs in
parallel as Tom suggests, or dump out the older data in Wiki markup
and post it on there. But I can't imagine what we'd want to do that
would even make us consider such drastic steps. Your example would
not be a difficult migration, for instance.
