We are currently running SolidWorks 2013 together with EPDM 2013, however we have recently purchased SolidWorks Electrical meaning that to use this we will have to upgrade to SolidWorks 2015 (as I believe it is unavailable prior to this version). We have been meaning to upgrade for a short while now but this has forced our hand a little. If we were to upgrade the SNL server and clients to 2015 but leave EPDM as it is, would this cause any problems? We would be looking to upgrade EPDM at some point in the future also but unfortunately now is the not the best time for a number of reasons.
Many thanks for any help in advance.
