Hi,
Q.I have read the article here http://www.symantec.com/business/support/index?page=content&id=TECH197426 and just want to confirm that there are no other "gotchas" to upgrading SEPM from 12.1.1 to 12.1.2. Basically, disable SEPM service on all servers, upgrade and fire back up, correct?
--> Prior to upgrade take a backup of existing SEP 12.1.1
Stop the Symantec Endpoint Protection Manager Service before starting upgrade process.
After successful upgrade you can take a backup again if required.
Q. My other question is, are we required to upgrade the Endpoint clients at this time or can we continue to run on 12.1.1 and they will function properly.
--> You can continue to run on 12.1.1 clients however it's recommended to have SEPM and SEP clients on the same version.
I hope it helps.
