So for zigbee this is very possible and I've recently done it multiple times without any issues whatsoever. I used to use a ConbeeII as my zigbee coordinator, but my server rack is located at an awful position in the house for coverage, so I picked up a TubeZB PoE EFR32 based coordinator [1] which has been incredible! I use home assistant, and it was trivial to backup the network, unplug the ConbeeII, put in the IP address of the new coordinator, and import the backup there and everything just continued to work. Then I had that die, it was actually the PoE portion which died, so I did the reverse and transferred everything back to my ConbeeII while I diagnosed and fixed it, then when it was fixed transferred everything back to the TubeZB coordinator. It actually took longer to get the IP address assigned on the TubeZB coordinator than it did to transfer my network each time, it was incredibly simple. I'm not sure for z-wave though. I do use it, but I've never had a z-wave gateway die on me, or had any reason to replace it where I wasn't also moving or something.

Good to know! One of the more specific things I was wondering is that when you relinked everything if HA would forget what's what or if it would hook the devices back up to all their automations afterward. I have some Hue bulbs which are Zigbee, but I've been considering getting out of Hue's ecosystem for controlling them.

  The names seemed to reset for some of my zigbee devices (interestingly not all of them, just some of them, it's likely something else going on and unrelated but I don't know for sure), but they still work in their original automations and in my UI everywhere that I have them.
