You can downgrade them though, but I don't know if you get to keep the old part yet. We'll be upgrading our first part later today. I'll try to post again then if someone hadn't answered this already.

I wouldn't invest in a workshop until you move unless you can spare the gil.
You can demolish the airship itself tho. I dont think anyone has done this yet however, so no idea if it returns the parts.

At the very least you will lose any ranks you obtained, as those are bound to the workshop/functioning airship.
