We recently moved, including a safe.
Unless you're used to bear wrestling, you need several things going for you:
With no details on how far, what type of flooring, what floor it's moving to, what it looks like from your driveway into the house, I'll take a generic stab.
A ***very clear path*** (height, width and turning / manuvering space) with very very few obstructions from where you're unloading it to where it has to go.
A furniture dolly will work if you can maintain perfect balance, don't care about busted hands or feet WHEN it falls, or more appropriately a very heavy duty hand truck with fold-out auxiliary wheels for stability that has a strap to maintain control.
Assume 4-6 guys to help unload it from your pickup or trailer. It's heavy and unwieldily. It's not that you can get all 4-6 around it, but more allows for no one to get exhausted which can be dangerous, and allows a supervisor to watch for issues.
Carpet can be a pain, so plan ahead.
Good luck. It's a pain if you try to do it yourself.
