Great. I would wait with the frags until you have the tank re-set in its new location. Put water into a bin and place LR into that water. Put the rest of the water into other bins (be careful...this stuff gets heavy...more smaller bins are a good idea). Leave enough water, doesn't have to be much, to cover the sand. Have some help on hand to transport the tank, bins, etc. If transporting a distance, be sure to have a heater in the bin with the LR to make sure they stay comfy during transport.
Once at the new location, carefully add water to the tank (use a plate or bowl to cut down on clouding with sand). If you've transported for a distance, let the water in the tank warm before putting the LR in...we ended up having to wait overnight to do this. When you're satisfied that the tank is ready, add your LR and the rest of the water. You will want to have some fresh/heated SW set up just in case as well.
Good luck. It wasn't as scary a project as I thought it was going to be.
Post questions if they come up.
