Should work fine. When I moved a couple months ago I had a new tank half filled with water and then brought over my canisters and sump with all the fish and half of that tanks water. Hooked it up filled it and put the fish in the new tank. No casualties. To the fish it was like being taken out and put back in during a 50% water change
Having the old gravel in the canister will go along way in getting the new tank cycled quickly.
