I need clarification how to manage the New License Model for P6 Version 7

  To all P6 administrators/Subject Matter Experts, Here are my questions surrounding P6 Project Management Ver 7: 1) While in the older version (P6.1), we have 24 Concurrent licenses and 122 Named licenses, a total of 146 licenses. I believe that our previous setup was covered by an existing contract.  I am still trying to find out where that contract is.  Now that we've upgraded to Ver 7, did we automatically lose the flexibility of the 24 concurrent licenses we once have? 2) If item 1 is still covered by an old but existing contract, what adjustment should be made to preserve the abovementioned flexibility previously present in concurrent licenses?
