My main reason for asking this is that on my ISY994w500 @ 5.3.4 many of my Z-Wave devices seem to have 'incomplete' or only partially-functioning nodes and I don't know if those devices would create identical nodes on my IOX and would I also get those same "improvements" to my Z-Wave nodes via Migrating? 

If anyone knows the answer or has experience with both scenarios I would greatly appreciate hearing it. I don't have enough (any) spares of my Z-W devices to test on my IoP.

I have roughly 20-ish Z-Wave devices and while I can't delete them all pre-migration (too much programming impact), I could delete many of them and re-create them after the migration to ZMatter-Internal on Polisy. 

Thanks all!!

You should probably do the migration. Worst case scenario is that if the nodes are still incomplete after migration you could always do a remove and include on the devices.

Be sure to do a Zwave backup on the ISY before migration, and make sure your Polisy firmware is updated prior to migration.

Agree with @Techman.  Although it would be better to start clean and install all nodes fresh.  If you have alot of nodes this is very time consuming.  If you just have a few, then I would just start fresh.

If you migrate, just fix the ones that didnt migrate properly, most likely wireless devices.
