Was the current ufer sized for the current 100 amp service you have now.
I'm confused on how the inspector would allow it to be used for the upgrade.
No, the ufer was undersized for a new addition. I know as an inspector it wouldn't be allowed. see my reply / question below.

I understand as an inspector you can't accept it as is. The general question I have is: is there a limit or safety issue with how many grounds a person can have for the main panel (or a safety issue if one of the multiple grounds are undersized)?
Let me put my question into this circumstance:
I have a separate house with an existing 100amp service that has a #6 wire ufer for it. My only project/permit for this house is to upgrade the main service from 100amps to 200amps and I will install code complient grounding rods and metal water pipe ground.
QUESTION: If I am not adding a new footer, am I required to dig out around the existing foundation/footer, jackhammer into the footing to daylight the ufer wire/rebar connection, secure a new #4 wire and then repour the "damaged" footer?
If the answer is yes, then so be it.
If the answer is no, then is it best to leave the #6 wire attached as another supplemental ground or should it be removed/disconnected?
