what is a stable SEP 12 version?

This issue has been solved. See solution.

I have been using 11.0.5 for about 2 years now and it has been very stable for me. I am looking to upgrade to SEP 12 and would like to know what the most stable version is according to this community.

I have about 600 desktops and 200 servers in my environment. They are all behind a proxy server that does a very good job of blocking majority of the malicious websites out there. In my current deployment, I use SEP AV + Truscan. I am looking to do something similar with the latest SEP upgrade. In SEP12, I am planning on using AV + SONAR only. I see that the most recent version is 12.1.2. Is this what I should be going to?

Thanks in advance.

Yes, the SEP 12.1 RU2 is the Latest version.

Before you Migrate to the SEP 12.1 RU2, it is important to understand what is new in SEP 12.1 and SEP 12.1 RU2 specifically.

What's new in version 12.1

What's new in Symantec Endpoint Protection 12.1.2

If you are planning to upgrade or migrate to Symantec Endpoint Protection 12.1.2, please take a look at the latest how-to article created by our very own SEP content council team.

Secondly, SEP 11.0.5002 is an older version and later there have been lot of updates with fixes in SEP 11.x as well.

What are the Symantec Endpoint Protection (SEP) versions released officially?

The Latest is SEP 11.x is SEP 11.0.7300

Hope that helps!!

Depends on your definition of stable.

I always recommend going to the latest version, as it contains all the latest fixes. Check here on upgrading to 12.1.2

11.0.5 was pretty good but did have some bugs that forced us to move off of quickly.

12.1 has been very stable so far.

I would go to 12.1.2

Sort of a bit redundant the question as when you update licencing requirements with symantec they will only allow you to download the latest from fileconnect.

But after testing each release that symantec have released 12.1 RU2 has been the one that has the least issues and the most direct upgrade path smiley

Please review ideas and vote there could be something useful :)

I fully support all above comments - going for the latest available version is always best solution as it has the most up to date fixes and functionality included.

Have a look at the requirements as well:
