The data loss angle is the one I am worried about as well. With the solution proposed here we lose the former history. That's why I was thinking we might want to check on why the field was there in the first place.
Should we just have a patch undoing the constraint for now?
I don't think we are losing anything by setting the biblionumber to the current. In the case of a serial having had 2,3, or more biblionumbers, we are only using the first one - so while one previous connection was "preserved" any future ones were not. Even with one change preserved I don't see any evidence that it was intentional -- You are receiving this mail because: You are watching all bug changes.
