I think several migrated to Pro 23 this way, using a Pro 19 backup. Step by step, protocol by protocol. You just stop migrating at some point so to speak
Just make sure to avoid flows running in parallel, to prevent weird things from happening.
There’s a great tool for that: with Flow Checker app, you’ll get a listing of all disabled flows. This way you can quite easy check which ones are disabled on both homeys, and which are still enabled on both.
And I’m sure nothing breaks literally.
You’d install Homesh app set on both Homey’s after te split up.
This way, you can control each Homey with the other Homey (both being controller and satellite).
But when you get the hang of webhooks combined with virtual devices, it might be easier to control stuff at the other Homey.
