Cleaning Sand when upgrading tanks?

[Quinster]

When I swapped my 180's, I shoveled (literally with a dust pan) all my sand into pails, did a quick rinse with tank water, then dumped it into the new 180G.

I saved all the old water I could, and put what wasn't in drums holding my rock back into the tank and ran a diatom filter on it for 2 days, stirring it a couple times a day, and changing the bed in the diatom at times every couple of hours when it plugged.

I have not seen any issues in my tank since everything was put back in.
