Can someone tell me what the proper procedure is to upgrade a late 2012 Mac Mini Server that has two 1TB hard drives, with an SSD and keep the lower 1TB HD as storage and not use it as a fusion drive with keeping the partitions intact for reinstall of O/S on the 1TB? I've seen so many different posts that I am unsure which is correct. Some say it will ruin the SSD, some say it can be done by you move the data with a clone program to the other drive then remove and put the ssd in and then clone it back? Whatever help anyone can give would be greatly appreciated. My unit should be here Monday. Got a heck of a deal on it for $290 shipped working condition with a 2.3ghz i7, 4gb, 1tb.
