There are really only 2 ways to transport a bandsaw safely, either upright and well bolted and strapped down, or, more simply, on its back (spine) with some home-made chocks or framing to secure it so that it can not twist or fall over on its side. Regardless, remove the cast-iron table for safety (and to lighten your load).
If you should need to lighten your load further, you can also remove both the upper and lower cast-iron wheels which will knock even more weight off of the bandsaw, just be sure to label which wheel is upper and lower and which side of each faces outward/forward so that you can reinstall them just the same later. Whether you do this really depends on how much help you will have versus how much you need to trim down the weight ... you can even go a step further and pull the motor if you really need too, but if you have 2 strong workers or several helpers, then you should not need to remove anything more than the table as the entire unit weighs in at around 400lbs.
During transport, tape the upper and lower doors close to ensure they can't possibly come open during the move.
