Hi - the need to rotate tomato crops depends on how much room you have. Commercial growers with large field grown tomato acres sometimes rotate but it isn't nearly as common a practice as it used to be since we now have many resistant varieties of tomatoes.

Home gardeners often don't have the space to rotate and honestly, even if we do have the room, many of us don't do it. Instead we amend the bed with lots of compost and the beneficial organisms it contains each year to control diseases. The exception is if you had a really bad case of soil borne fungus disease such as black rot or stem rot in the previous year. Since many of the common tomato diseases are airborne, rotation doesn't help prevent them much.

But if you have the room to rotate to a new location it sure can't hurt to move them 6-8 feet away. Just depends on the room you have.

I have linked many of the previous discussions on this question for you below if you wish to review them.

Enjoy your garden! ;)
