Review Comment:
I started with that approach and then in testing I ran into a problem where
the upgrade code could not write to the metadata table because of the metadata
table constraint. So I had to make the constraint code still use these columns
and the package it is in can not access the Upgrader (constraint is in server
or core jar while Upgrader is in manager jar).
So I ended up settling on this approach of isolating the columns in the
MetadataSchema class.
