Hey Robin and @martijnpoppen ,
You already can exchange (export/import) flows with The Flow Exchange(r) - Exchange Your Flows with Others!, also on your own homey or an old homey.
If Athom will not support migration, ill make the few changes needed to fully support migration from and old to new device.
But, for a large part, The Flow Exchange(r) can already do what you want. I use it a lott to copy/paste flows that are the same for al rooms, but with different devices.
Because during import, you can replace devices (or tags or apps or rooms) very easy and all references in the flows will be changed for yours.
