We are looking at upgrading out Exchange 2003 Server to Exchange 2013. We are currently running Email Security 7.3 and I do not see a clear path to upgrade to the latest version.
I have seen some discussion about moving to an appliance but not sure if this is the only path or if there is a software download that we can run. If the appliance is the only path, then how does our current licensing work out since we have 841 days left?
Thanks
