I would assume that the password file formats have not changed, so I
would assume that the files can just be copied over.

You could make the password related files immutable on one box and
have password changes only be done on the other, then synchronize the
password files from the master to the slave frequently.  Frankly, I'd
avoid that issue by telling users that passwords cannot be changed
during the migration and make the migration phase short.
