             Hi, 
Registration of Partnership firm can be done at any time during the continuance of Business. There is no provision in law which stipulated that the old partnership deed should be registered in order to register a new one, for the first time.
In my humble opinion, There is no need to register the 2012 deed first to get the new updated 2016 deed registered.
You can just get the updated version of the deed registered with the ROF because the final deed would be worth consideration, what happened before may not be important for the purpose of registration.
