Thanks for the comment.
I spent a lot of time looking for information using the search function in the forum, but unfortunately I came to the conclusion based on this: z-wave issue that the z-wave network is not stable. Then I don’t dare to do the migration. Zigbee and other devices are probably not a problem.
But Z-wave devices are apparently a problem.
It is clear to me that the migration will not be completely without problems. Thanks again for any advice.
