It was standard practice during early access phase [[HowTo] Homey Pro (Early 2023) - Migrating from Homey (Pro) (Early 2016-2019) (With Early Access) - #16 by Cuprani](https://community.homey.app/t/howto-homey-pro-early-2023-migrating-from-homey-pro-early-2016-2019-with-early-access/77516/16)

My understanding of how this works is that the migration from 2019 → 2023 means that the z-wave network on 2023 is an exact carbon copy of the z-wave network on 2019. So the 2023 doesn’t “take over pairing of your devices”; as far as the devices are concerned, it _is_ your old z-wave controller. This is also why you cannot have both the 2019 and 2023 powered on at the same time after migration without serious issues - you would essentially have two identical controllers trying to run at the same time.
