For anyone having this issue : Shut down. Pull out both RAM drawers. Remove all RAM. Remove all dust (preferably by dry compressed air). Carefully but firmly re-seat the RAM on the drawers. Re-seat the RAM-drawers in your Mac Pro. I've had this random shut-down issue right around the time Steve died, so it could also be related to his reality distortion field energy playing havoc on my Mac Pro ... but somehow I doubt it ;-) (The restart occurs after an unscheduled shutdown, if you have automatic restarts enabled in the Energy Saver preference panel.)
Yes - Make a clone on the new SSD first using an external housing, start up from that disk, then split the internal Fusion Drive in the Mini in its HDD and SSD components using Terminal. Reformat the internal SSD and HDD. Shut down, and replace HDD with the new “external” SSD. The SSD-part of the Fusion drive becomes an extra internal SSD. For fastest performance, put OSX on the faster ex-Fusion SSD and datafiles on the newly installed SSD.
If you haven’t done the upgrade yet, a standard SATA 2,5” interface works - the I , II, III indicate the speed, not the connector, and they are backwards compatible

Dunno - Bombich.com Carbon Copy Cloner (my go-to clone app for years) clones them perfectly and has done so for years.

I should have used this far more detailed and useful guide than the general iFixit teardown, yesterday. Oh well, job done and it even works again.
