Verified w/5.0.3 from bk

This is a known problem, since ACC has been modified not
to store primary key data in 5.0 (this is only stored in TUP now).
Can you verify that a rolling upgrade still works, as well as restoring
a 4.1 backup on a 5.0 system.
If these work then this short-coming is not a huge problem, we still
have one on-line and one off-line option how to migrate.
