FWIW, I don't know what the official guidance on this is, but when I moved my hub about 30' and from one room to another months back, I just let the hub sit in the new location for a day or two w/out making any changes. The Z-Wave Plus devices are designed to re-route on their own if they don't have good connections, and Zigbee will reconnect (they go into "panic mode" when the hub is off for 20 minutes) so I wanted to give the devices/hub a chance to work things out on their own. It's been a while so don't remember exactly when, but I also did a full shut-down/reboot a little later "just in case."
I never did any Z-Wave repairs and things kept working.
Did you have any issues w/devices not working/not reporting when you ran the repair, or just doing it proactively?
Do you have any devices on the Z-Wave Details page that are missing a name or routing info (last column)?
I had something similar happen. I moved two z wave devices from one hub to another hub as well as their physical location. I rebooted my hub and waited a few hours. When I tried to run repair, every z wave device was unresponsive. I rebooted waited an hour and tried again. Same thing. One more reboot and things started working again.
I am having similar issues myself. When I run a repair on random devices it will get all the way to assigning route #5 and then hangs from there. At this point all zwave becomes non-functional and the only way to recover is a power cycle.
I think that they (that is the support people) should include a sequence in the upgrade procedure which would "turn off" the Zwave Radio (for the minimum length of time), since this seems to "fix" things for some people (me included).
They are smart people, I'm sure they can do it.
