Zipp vs Roval Wheels
if I wanted to swap Roval wheels from 2014 and 2016 with new zipps could I without issue?
dont want to have to keep making adjustments to bike to swap between wheels
if I do have to adjust what has to be tweaked?

Disc or rim? What bike? Specialized used a proprietary SCS hub on Roval wheels for their early disc bikes. You would need to replace a hanger if that is the case.
If those are rim wheels, you should be able to switch them without any issues.

^^^ This
If you are buying complete wheels it will be an issue. If you want to build wheels you can use a hub designed specifically for these bikes.

Rim brakes on rovals that are 2-4 years old
zipps would be new
so the hubs are different widths?
meaning I would have to adjust brake width?
anything else to adjust?

Why would the width of the hub impact the brakes? If the rims are the same width, your brakes won't need any adjustment. If the hubs are different widths, you'll likely need adjust the derailleur.

Adjusting brake pads is sop.

The hub width is only different on Disc brake equipped bike/wheels.
Since you have rim brakes, there is no difference, you will be able to switch your wheels back and forth. The only (minor) thing might be rim width difference, affecting your brake cable length, but that is a very simple on-the-fly adjustment.

Sometimes you luck out. Sometimes you don't.
If full rim brake then you might have to adjust brakes depending on the rim widths. Most I know run the narrow width with the brake quick release cam closed and then the wide with it open.
The only other adjustment is shifting. You may need to make a small barrel adjustment on the rear derail. If the difference is large you may have a small issue with limits but doubtful.

Disc brake hubs with 135 OLD use 44mm chainline. Road bikes with 130 OLD have 41,5mm chainline.
Shimano specifies 41.5mm chainline for hubs used with road groupsets. Using a 135OLD hub with 44mm chainline means the hub chainline is out of spec. This can result in chain rub, poor shifting or the chain getting caught on the shift pins on the back of the front chainrings.
This is what Specialized encountered with SCS bikes.

I'm sorry but it's not that simple.

Even rim brake to rim brake, different wheels are different widths, and you may have to adjust the brakes. If I know I'm swapping wheels back and forth, I'll set both bikes up for the narrower wheels, then use the quick release to open the up a bit on whichever bike happens to have the wider wheels at the time.
But this does get tiresome after a while.

If it is 130OLD road to 130 OLD road then it's a crap shoot. A little barrel adjuster magic may be in order.
