It looks like you are replacing the tank. If that is the case, and you have time, consider setting up the new tank before you tear down the old one. If you don't have the 55 gal tank yet, you could even consider getting a larger tank, but that another set of issues.
You'd need an additional stand, and a few extras, but that's about all. Then set up the new tank in it's new location, optional you could use one of those exotic substratas. Add a heater if you need get the temp correct. Once the water is ok, then move one of the HOB filters. Don't clean it too much. You want it to establish the bacteria base on the new system. Now wait a week or so.
On moving day, move the lighting, CO2, other HOB filter, fish, plants, rocks, and other decoration. Once everything is in it's new home, you can tear down the old tank. note that you don't have the problems of actually moving the large tank, or washing a lot of gravel on moving day.
Not everyone wants to end up with a lot of extra equipment. so if an additional stand is out of the question, I would have a supply of new water that is all set to go at the new location. I'd use one of those large round rubbermaid trash cans, cure it, just in case there is anything in the plastic, and fill it with water, a powerhead, and a heater prior to the move.
