True HFS+ is well past it's usefulness but APFS is not going to be much better. they should have gone for a solution close to ZFS and really put the wind up their Dev Teams to make it a rock solid release Day one. (y'know like they used to) Agreed I Never Migrate until .2 release usually due to the security patches they missed in the first round. Speaking of Which I believe 10.13.2 should already be out at present. now to see if there is a way i can use a third party tool to manually backup my system for my migration from Yosemite.
