I had symantec endpoint protection installed on my server and 10 pc's. one year later i got my renewal discs and license. the renewal disc is a few builds later. i think it was 11.0.4 and i got 11.0.6. I inserted my new disc and installed on top of the older version. it went trough what looked like an update process. After finishing i pushed new installs to all the clients. After doing this i have know communication with the server. all cliens say offline. no where could i find any upgrade manuals on the web.
Did i do the upgrade in the correct way?
Why is my clients not communicating?
