All you can really do is get LOTS of containers and make it fast for temp reasons. The LR will need to be transported wet, of course, and if the trip is somewhat long you'll have to make sure it stays at an acceptable temperature. When I swapped tanks, others advised me to only keep a little of my sand and use the rest new. I'm glad I did; it made things a lot easier. I'd absolutely do it that way if there was a move involved.
Also, no matter what you do there is the possibility you'll have a mini-cycle. Do you have a lot of livestock?
