Too late now but I wrote up my process for doing a similar task. Took lots of screenshots and notes before hand. From DTH to Edge Migration tips or tricks?
Note that devices vary on what they reset/re-initialize on an exclude vs factory reset. Some reset everything on exclude, others leave parameters alone. Some don’t do a factory reset after a firmware update either, which can lead to all sorts of odd behavior.
Most of the built in device handlers for zwave tend to leave parameters alone except for very specific cases. If its not settable via the App->Settings, its not likely to be modifying the device. Compared to Zigbee, parameter indexes and options vary widely between implementations. Even when handling specific logic of a major player (Leviton for example), it tends to be something non parameter related. Thus why we like using the manufacturer specific drivers instead (Zooz, Inovelli, etc).
