Let's see if I understand this...
You suggest creating one or more views (view as in sql view, virtual table)
that contains the the data of interest
(stem names, group names, group memberships, group and stem privileges) from
the grouper v1.1 database, and use this
view to periodically update the data in the grouper v1.6 instance?

I have to check how this fits into the rest of the picture here, but it
sounds like that may work.
