I have just migrated my zwave network from HomeSeer to Home Assistant but I’ve only 20 or so devices, so not the bigger task you have. I had 3 znets, but apparently you will only be able to use one as-is with Zwave JS. I followed the guide here: Zwave-JS-UI on Znet via docker to install ZWave JS-UI on my znets and couldn’t be happier with the improved performance and, once you get accustomed to it, the functionality of ZWave JS-UI. I followed the strategy suggested by @PeteRage above and did a piecemeal approach. I would suggest, unless linux stuff is your thing, to test run with a new RPI 3B and zwave hat and get that running first. While I haven’t any firsthand knowledge of doing so, supposedly you can transfer the zwave hat and maintain your associations. Probably best to seek out other sources to confirm this.
You should take a look at this: Z-NET Integration with Home Assistant, but again, only one znet in ZWave JS. Other posters here in the forums have described how they moved their one znet back and forth between Home Assistant and HomeSeer to facilitate their migrations.
