I'd suggest to just make the change. Things will immediately feel different due to the gauge changes. To bring the action more in line with the old feel you may have to slightly tighten the truss rod to adjust for the increase in tension, and you might have to do some slight bridge tweaking (height and intonation).

If that is the gauge set you want to run and aren't running it now then a few minor tweaks may be necessary but it's nothing to be overly concerned with. It's all quite simple to remedy on your own. You don't need to know rocket science - just who to ask for advice...and 2 allen wrenches and a screwdriver.
