How far along is it?
You could bottle it for the trip and unbottle it when you get there.
Don't prime, of course, especially if the gravity is still moving. 2 or 3-liter PET soda bottles might be your best option - they will take a huge amount of pressure if it is still fermenting significantly, and are hard to break. Toss them in a cooler with ice for the trip and they shouldn't pressurize much. Siphon (to reduce splashing/oxygenation) back into fermenter at the far end.
If it's well into aging (moved on to secondary, gravity stable, but your recipe calls for months in secondary) just prime and bottle and let it age in bottles.
If you start a new batch at the far end, you can fill the fermenters for the old batches with carbon dioxide from the new batch (use a blowoff hose into the carboy or bucket) to reduce issues of oxygenation as you put the beer back into the fermenters.
