My old system has connections G, B, O, R, W, and Y. I am unsure where the red wire in B should go and where the white wire in O should go. Is the white in O a common wire (C)? Should the red B wire go into O/B?

Hi BJM,
Thanks for posting and sorry for the delayed response.
Could you post a photo of your old thermostat wires and provide the exact make and model of it? Also, you could try checking if your system is compatible with our Nest thermostat with our online Compatibility Checker.
Best,
