Are you talking about moving it down a public roadway? If so, you had best check on permits to do so. If you do it without you will be responsible for any damage done to the road, the right of way or the private property boardering the movement.
The DOT also takes great pleasure in stopping illegal movement and will slap you with so many fines that it would be cheaper to buy the property where the building is.

That also means you aren’t going to use a span of 2X6 to move it, you’ll need a real company with I-beams and dollies.

The good part of this is that you could take the building apart and as long as the widest part is no wider than 102” on a main road, you should be fine.
