Tiered pools should be able to do this for you. It has been dis-encouraged as a performance gain (ie, the reverse when you have spin drives and want to put a ssd pool in front of it to get ssd perf but hdd price/storage) in some cases, but if you do it for migrations it should probably be worth it, given that a slight perf hit on the backend drives would be acceptable to be able to save money compared to all-ssd pools I guess.
