Albertareef has it right. Do it quickly and be prepared. You'd be surprised what can happen when you are moving a little piece of the ocean.
I have moved a 29/75 gallon tanks before and it is a pretty straightforward process, but nerve racking. If it is within the same town and during the summer, I don't think you will have to worry about temperature issues.
All I did was,
Make sure the location the tank is going is ready to go. I.e. doorways cleared, 20% fresh saltwater up to temp (with extra, just in case), extra buckets, pre-washed sand, multiple power strips etc.
Drain old tank and put livestock in labeled buckets and separated appropriately. In my experience, I've had more fish die than corals in moving because of stress. So, I'd catch the fish last and it's easier to net them with there is 6 inch of water left.
The sand is a pain because it is full of detritus. I've always replaced at least 50% of the sand and kept some of the top layer for the bacteria. Then thrown the rest in another bucket with water to sift for inverts after I re-setup the tank.
Transport tank to new location.
Setup tank, put pre-washed sand in, add a little old sand, put the rock in with coral and lastly, add the fish.
I bet you could do the move in two-four hours. If you need any help, let me know. I am close enough to Salem that it wouldn't be an issue.
