How to upgrade your SEP11 license to SEP12 online

http://www.symantec.com/connect/articles/how-upgrade-your-sep11-license-sep12-online

Hi miadmin,

Licensing was new to SEP 12.1: SEP 11 did not have a license infrastructure / licenses that need to be applied.

By the way: SEP 12.1 SEPMs can manage any SEP 11 clients in the organization until those clients are upgraded to SEP 12.1.  There's no need for a seperate SEP 11 SEPM just to manage SEP 11 clients.

Hope this helps! &: )

thank you Ashish Sharma & Mick2009.

so my product on licenses document is

"SYMC ANTIVIRUS CORP ED WORKSTATIONS AND SERVERS 10.2 NODE ESSENTIAL- 12 MONTHS EXPRESS BAND C  " (50 license) it already expires since Mar 2008.

And the last version befor i installed V 12.1 is version 11.0.4

How can i use old license with out purchase?

Can i still use old 50 license on SEPM v12.1 ?

Because now i already activate new 60 licenses, but after that it show

      - Total Purchased (60)

      - Seats Used (50)

      - Seats Available (10)

This mean i cannot use old 50 license?

please help me again, i'm so confuse.

Yes you can't use your old SEP licence in SEPM 12.1.

SEP 12.1 and License Concept

http://www.symantec.com/connect/articles/sep-121-and-license-concept

Long time ago we bought 50 licenses of SEP and we install SEPM and manage for 50 license in version 11.0.x.
and now we just bought 60 licenses of SEP V12.1.

So when was the 50-seat license for SEP 11.x due to expire?

Can i still use old 50 license on SEPM v12.1 ?

Because now i already activate new 60 licenses, but after that it show

      - Total Purchased (60)

      - Seats Used (50)

      - Seats Available (10)

This mean i cannot use old 50 license?

What it looks like to me: your 50 11.x clients are now reporting in to the 12.1 SEPM, and that's where the some of the license count is going.

If your 11.x license is still valid, I would probably give Customer Support a call to look into it. Check here for local phone support numbers for non-technical support: http://www.symantec.com/support/assistance_care.jsp

For this issue, now i understand.

After i consult with Symantec customer support by phone.

I cannot use Old SEPM and New SEPM on same server.

because the newest version will be replaced old version.

Thank you for everyone for your answer.
