When you migrate or upgrade the license, it will not impact any existing dashboards you have created. Essentially, GMaps Plugin and CMaps Plugin use two different mechanisms for authorization and tracking page views. Full versions of both products can run in production side by side. For development you can simply swap out the XLX files as needed only when you use the GMaps Plugin Bundle Developer EXE. For trials, we use the same key system and one key would work in GMaps and CMaps.
