I am a co-op student doing my internship and I have been given the dreadful task of upgrading people's Windows Server 2003 or older versions to Windows Server 2008 R2 or higher. However, most users are very aggressive when it comes to letting me upgrade because they may not care about the version of server they are using. For my requirements though I have to do it so I wanted to ask someone what arguments or incentives could I use to successfully convince my users to let me upgrade their server? Does a regular user benefit greatly from stability? Performance increase? What can I use to my advantage to aid me in convincing them?
