Comment 4 for bug 1700731

At this point we don't support having a subnet go away and come back with a different identifier. It would be possible to edit the database directly, and we have some plans around improving our space support (being able to add/remove/update existing definitions), but that work has not been started yet. It may be that we can get to some of this in a 2.3 time frame (in the next month or two).

To handle the immediate issue, we either need to edit the database, or rebootstrap.
