All is well now. I had to upconfig the switch, update the primary image, thus making both prim and sec match the stack. After that was good to go, I then enabled stacking (without the easy config), enhanced protocol, master capable saved, removed power. Then I add it to the stack, powered it up, the master stack recognized but I needed to config a slot number and Stack MAC, it also appeared to do some sort of auto synch on its own, rebooted switch overnight and everything is good to go. I think I will avoid the synch command in the future, as it seemed to bork the new switch every time I ran it.
