Sorry to hear of your situation
Dont worry about taking any water...just make sure your filters are not turned off for more than a couple of hours ...you could run a battery pump into the filter to keep it going.
When you get to your new place fill the tank up but make sure you treat ALL of the water. (I recommend prime)
Also DO NOT clean your filters out in this process....look after the bacteria that's all you need to do
ADDED...Get a large container to keep your Oscar/Oscars in for a couple of days. Just make sure the filter you use on the container is mature with bacteria.
You could squeeze your current filter pads onto a smaller filter pad/pads for the container.
