you should not relocate the sand, it should be rinsed 100% clean before re use, and even better, fully replaced.
sand stayed in contact w that dudes phosphate level choices, his waste built up...start clean, you have a chance.
you can rinse the entire sandbed all at once and transport zero waste into your tank, or you can change it all out at once, not in sections, for the new tank. It does not cause a recycle we have a 20 page action thread on it

the thread has working examples of tank moves, multiple ones.
don't transport any old sand, rinsing it doesn't cause a cycle, nor loss of bac that matter.
its not that you need some of the current bacteria from the bed carried over
you need none of it, see our works above.

that's a death knell in reef moves never accept it, plan against it. envision a thread doing for pages the very type of move going on here- able to track start to finish[/QUOT
I completely agree him on the the sand. I think the sand along with temp are your biggest factors to a tank move. I had a tank in college and did bare bottom or pitched the sand every time i had to move my tank. I actually did multiple 13 hour drives with mainly acro's with no issues.
