Thanks for the feedback, Ron and Brian.

I think the current data should be reviewed, and migrated as it seems
sensible, expecting that some will be dropped or modified in the process.

I don't see a value in the wiki history there. The value in that seems
to be in having "backups" in case you want to revert a page. In this
case, the backup is that the old wiki will don't go away right away, and
will be there for reference as we refine the new wiki.
