Thank you for your replies. To be more clear, I have 12.1.2015.2015 installed on the SEPM. I have auto upgrade already configured as Brian posted. How do I go about upgrading the SEPM?
Following the link i metioned above for Obtaining the latest version of Symantec Endpoint Protection or Symantec Network Access Control, I got to the screen where I choose what it is I want to download. I selected Part 1 and Part 2, downloaded and then extracted the files. I am hesitant to proceed from there as I don't want to end up doing a complete reinstall on the SEPM. Will this just end up being an upgrade?
