If I were the Anu people, I would focus on having a seamless compatibility layer that could manage Git <-> Anu repositories (there are undoubtedly many headaches that would occur synchronizing the two different models). This would allow developers to silently interact with ongoing git repos using the "better" tool. Getting wholesale migration to a new platform seems a significant challenge, but allowing developers to slowly build mind share with an improved workflow would be possible.
