Success is the transfer. I was unable to get the Aeon Backup software to do a restore to the LInear Zstick. But the controller ‘shift’ was pretty easy.
For anyone else, there is some good instructions by @higgers here:
Essentially, your adding your new controller as as Node on your existing Gen5 controller creating a secondary controller. Then you do a ‘shift’ to make the Linear the primary and the Gen5 the secondary. Then after that you set the Linear to be Node 1.
When I was done, I actually then just restored by backup file back to my Gen5 stick, and is not my current backup.
I put the new Linear back into OH2 running in a VM on ESXi. Needed to change the port in Habmin to the new setting ( ttyUSB0 for me) and then all nodes in OH2 popped back up online.
Now I’m off to installing the zigbee binding and trying to pair an osram rgb bulb.
