My experience
Finally decided to try the migration earlier this month.
Lots of warning and errors. My strategy was to take the plunged and manually fix the issues. Over a period of a few days, was able to get all devices online and renamed - updated automations and all was good for a few days.
Yesterday, noticed that almost all wired devices were marked as Dead. After many failed attempts to correct the situation, decided to roll back to Zwave(Deprecated)
Backstory: Migrated from Vera a few months back to Zooz stick on Pi4. Automations and devices have been stable for months.
I have ~30 zwave devices and most have been flawlessly operating for close to a decade.
