Just preserved the filters in a pail (5 gallon pails are nice they are cheap and commonly available) with tank water. It is fine if the filter doesn't run 3 or 4 hours during the move. You can also put the fishes in pails. In fact i've kept my fishes in pails for a month with a sponge filter with no issue. You will have to completely drain the tank. Depending on the type of substrate you might have to replace it (very fine sand will sometime have anarobic bacteria and if this is disturb it can foul the tank; coarser substrate like eco-complete will move easy enough). What I did is remove all the substrate and put it in pails move the tank resetup the tank - keep the fishes in a pail or two (depends on what kind of fishes you have) until they were ready to add to the tank. One thing I would definitely do is test the water at the new location for ph, gh, kh and if it is similar to your current water you are good to go - if not you might have to slowly adjust the fish to the new water (a lot depends on what your stocking looks like and the type of filters you have).
