Chainset / chainrings: compatibility 10-speed to 11-speed?

Quick compatibility question: I currently have an older SRAM Rival 10-speed groupset on my bike. I'm contemplating replacing it with the new 11-speed Ultegra or possibly 11-speed SRAM Force. Can I simply use the current 10-speed chainrings with the rest of the drivetrain upgraded to 11-speed?

My current 10-speed setup with 52/36 110BCD SRAM rings.

Or do I need to (or should I anyway) bolt some new 110BCD 11-speed chainrings on there? Or do I need to actually change my whole chainset/crankset also due to new spacing issues?

I'm not entirely sure on the differences in this area...
