Hi,
We were also in the process of considering migration of our interfaces from 7.11 to single stack 7.4 which we are using for our B2B scenarios. Other priorities have crept in the way but reviewing the current content for naming conventions, redundancy, etc. is an opportunity we will have. Had a chance to push really hard the best practice especially on naming conventions probably to the dismay of my team. 
Regards,
Ryan Crosby
