I think I have my plan down, but I have a few minor concerns.
What do I need to download from fileconnect? From the demo I saw, looks like all I need is the Symantec_Endpoint_Protection _12.1.2_MP1_Part1_Installation
http://www.symantec.com/connect/videos/sepm-11-ru7...
At one point during the upgrade, the wizard says it's "Creating a new database"; does the account doing the install need any SQL rights?
After the install is complete, I know SEP 12 have default firewall rules. Do these rules take affect immediately for all existing clients or only when the clients are upgraded to 12?
My plan is to upgrade server1 (physical) from SEP 11 to 12. Install SEP 12 on server2 (new VM) as an additional management server. Drop server1 once all the clients are reporting to server2. With this strategy I should be able create a replicated partner off of server2?
