Especially being a bit higher than 208, you should not experience any problems.
What machine and controller are you retrofitting?

I just moved into a new shop with 208V 3 phase. My previous shop had 230V single phase with a rotary phase converter. Actual measurements in the new shop are 213V between phases and 120V to neutral.
Nothing except my TIG is explicitly rated for 208V. I have several 3ph motors (Bridgeport, air compressor, lathe, grinders). I'm also about to begin retrofitting a CNC milling machine.
What do I need to know?
