I am very much afraid that the upcoming Move feature will work very much like the way the current Demolish system works, requiring you to pick up all furnishings and lose private rooms/workshops. My prediction is that the only benefit of the Move feature will be that you won't have to pay for the new plot/housing permit.

I have no evidence for this, I'm just basing it on the way SE has handled all housing features up until now. Who knows, maybe this time they'll surprise us and put in a feature that's convenient and user friendly.
