  Why not migrate all user information to the new database, and switch
from the old one to the new one at 2am one day?  If something goes
wrong, you can switch back, and re-do the migration.

  RADIUS doesn't return "notfound". It returns "REJECT" or "ACCEPT".
So what you want to do can't be done the way you want.

  I don't see why you wouldn't just migrate all of the users at once.
