So I've been trying tonight to migrate my Unifi protect from my Dream Machine to a dedicated NVR. I followed some guides that talked through how I could preserve all of my data and took great care to preserve it all.
I've just seen a re-install of the Protect app (Recommended on their forums) slowly format all of my data despite it being mid way through trying to mirror the storage.
I am really feeling quite fucking done with this thing now.
