Tenant migrations and the other migrations listed above happen via the recipient primary, which means that as the data is copied over the recipient primary inserts it. As long as the recipient primary knows that the collection being copied has recordIdsReplicated:true (which may be something we need to implement - the primary probably won't know this), then from that point onward replication will ensure that the recordIds are the same (thanks to SERVER-78348 / SERVER-86046).

However, the recordIds will NOT be the same as the recordIds on the source cluster, which should be OK.
