We currently use the SolidNetWork License Manager from FlexNet (v22.0.0.5018) to manage our network licenses for SolidWorks 2014.  We're planning a 2015 upgrade soon.  Will the license manager rev need to be changed as well during this upgrade, or can we simply load the 2015 license file into the existing license server?  If so, can we load the 2015 license file into the server before the upgrade, so the 2015 licenses are staged ahead of the upgrade?

Thanks for any help/guidance you can provide on this!
