Clarification about AFP and Kanaka proxy

When installing Kanaka it says that if a proxy already exist, it will be re-provisioned.

Do i need one afp proxy and one kanaka proxy on the same server? or will one will a single 're-provisioned' proxy handle afp and kanaka jobs?

Always assumed one would be sufficient but don't want to 'assume' to many things..., so thought I'd ask.

Thanks.
