If I want to update Server "A", but now it only has 1 single child CPU, with ID "3", if I did a simple merge, I would have CPU "1", "2", and "3" in the database instead of just having CPU "3" like I intended.

You can do em.find(<Server "A">), then compare the collections of CPUs and adjust accordingly. It's not pretty but better than remove/insert solution.
