A warning, if you are merging 2 computers into one, make sure that the earlier registered computer (the one with the smaller number) doesn’t have any WU crunching on it, because the server will cancel the WUs after the merge, and you will get no credit for them. If there are WUs crunching on the later one (higher number), the WUs will be completed. During the merge, the server will retire the earlier computer and keep the later one. Yes, this happened to me.
