Contact your local safe dealer,, they have walking dollies.and should move it for a couple hundred bucks.I have my safe on a floor over a crawl space and no issues. When I moved, however my plan was to put my safe in the “bonus room” over our Garage. The moving company wouldn’t move it up the stairs no matter how hard I tried to persuade. It’s still downstairs but I still want to relocate it upstairs - I think it will make it!
Buy a knock down safe to start with. Moving problems over.
