In GRPC Can I extend same implementation class two places, because I would like to deprecate the old flow.

Trying to use GRPC implementation stub in two classes, can I do that?

You can only use @GrpcService on one of them and must handle the delegate to the other impl yourself. Maybe it would be better to use 3 impls. One that contains the delegate logic and the other two with just the buisness logic.
