Sage 300 2014 Upgrade from Advanced licenses to Premium Licenses

Didn't find a clear answer on this in the forum yet, We want to upgrade  from Sage 300 2014 advanced edition to Premium . We have Intercompany premium module and GL Consolidations previously installed and they are Premium Edition.  The overall reason for the upgrade is to get more than 10 users in Sage at one time. 

As we have about 15 pc's affected , hoping that we don't need to uninstall, and reinstall on each PC.

Is it possible to install the premium licenses  without having to reinstall  all modules to  touch each workstation? 

thanks in advance!
