Rotating tires on a dually

Everybody I know with a dually stops after the first or second rotation. The reason is that gravel and debris thrown up by the front tires hits that gap between the duals and chews up the exposed 'angled' portion of the rims, rendering them unsuitable for use on the exposed front axle.

As for the pattern, I would go with what the OEM recommends, should you choose to do so.

As for the physical how-to, there are a dozen different ways, but I don't think that's what you're looking for...
