Clicking that link gives us "The requested page could not be found."

Sep 25, 2014 08:03 AM


Original poster is not much active on the community.

Hece we have decided to start a new blog to keep it more updated.

Here it goes: https://www-secure.symantec.com/connect/blogs/symantec-endpoint-protection-release-details 

Sep 25, 2014 07:33 AM

Needs updated for the RU5 release please.

Aug 07, 2014 09:45 AM

It's now updated.

Aug 07, 2014 09:21 AM

I will request the thread owner to update with this info.

Aug 06, 2014 10:35 AM

The zero-day patch/version (12.1.4112.4156) should be added to this listing.

May 13, 2014 07:13 AM

I've done the same. And its confusing because in the versions.txt in the download it states:

SEP Client Version 12.1.4104.4130
SEPM Version 12.1.4104.4130
SIS Version 12.1.4104.4130

But it never adds new packages for distribution during the update.

I also tried installing an unmanaged client from the "DVD", and it still states version 12.1.4100.4126

Please stop confusing your customers... :)



May 06, 2014 08:06 AM

RU4 MP1a did not contain updated client patches.  RU4 MP1a was released to address the Heart Bleed vulnerability which is a server side issue.

May 06, 2014 05:56 AM

I've upgrade SEPM to 12.1.4104.4130 (RU4 MP1a), but I didn't see any new packages. Is it normal ?

Where can I find SEP Client RU4 MP1a Client-Only Patch, if exists ?



May 02, 2014 11:16 AM

Hi, what's new in RU4 MP1a ?

Apr 11, 2014 03:55 PM


Apr 11, 2014 03:52 PM

this appears to be missing 12.1.4a for SEPM

Oct 01, 2013 08:51 AM

May as well wait for the latest version, RU4

Oct 01, 2013 08:23 AM

I am now deciding to either to upgrade my clients from SEP 12Ru1 ro Ru3 or must I wait for Ru4??

Sep 30, 2013 03:45 PM

Is SEP 12.1.4 releasing in October on schedule ??

Jul 17, 2013 08:06 AM

There has been no mention on an official date.

Jul 17, 2013 07:59 AM

Any information when the next release will be available? The one after 12.1 RU3.

Jul 16, 2013 04:54 AM

Thanks for Sharing 

Jul 10, 2013 02:37 AM


Check this document - it says 7.1 sp1a starts support for SEP 12.x

Does IT Analytics Symantec Endpoint Protection Report Pack support Symantec Endpoint Protection 12.x?


Jul 10, 2013 02:25 AM


You can find the release details about SEP products under this link:


Just select the version you are interest in and check the dates.

Unfortunately, I am not aware of the next major releases to come, but I am sure this information will be shared once some dates are known.

As for the NetBackup, you should ask that question on NetBackup forum.

Jul 09, 2013 09:51 PM

May I know if Symantec IT Analytics is availabe for the below version?

 RU1 MP1


 May 2012


Jul 08, 2013 01:08 AM

Awesome......Really good Article.

Jul 08, 2013 12:31 AM

This is great, exactly what I was looking for.

1. When will Symantec stop supporting v12.x?
2. Is there any word on when the next major release (i.e. v13) will be released?
3. Is there a similar table for the NetBackup releases?

Many thanks.

Many thanks Pete,

I Really need this version for this solution:

Migration from Symantec Endpoint Protection 11.0.5 or higher to Symantec Endpoint Protection 12.1 RU2 and removing Network Threat Protection causes network instability
Fix ID: 3063813
Symptom: When upgrading from a later version of Symantec Endpoint Protection with the firewall component installed to a Symantec Endpoint Protection 12.1 RU2 install package without the firewall, the network may not load upon reboot.
Solution: Updated the migration mechanism for removing Teefer3 components from prior Symantec Endpoint Protection versions during the firewall uninstall.

Jun 04, 2013 09:59 PM

Thanks Manish !

Jun 04, 2013 07:49 PM

BenjaminBvalani  please post as a new forum question.


That version was a "beta" version.



Jun 04, 2013 05:27 AM

Dear Techies,
Am using SEPM 12.1.671.4971 recently i have been getting old alerts of over 2 months, they keep coming every now and then, but when i check the SEPM Dashboard i can only view the very recent ones, but on email alerts i am getting the old ones and new ones, what could be the cause of this ?
Kind Regards

Time to update ! SEP 12.1 RU2 MP1 is out !

Jan 14, 2013 12:33 PM


The last section, labeled SEP SBE 12.1.x,  should be removed.    It repeats the SEP EE 12.1.x  info from the top, but adds an incorrect "SBE" to its heading. 

SBE versions are in the form "12.0" and SBE information is listed just above this.



Dec 14, 2012 12:46 AM

Hi Mithun,

Thanks for your views.

Dec 03, 2012 04:45 AM

Regarding RU2 (support for window 8), how is it installed on a SEPManager 12.1 (12.1.1101.401)? Via liveupdate? Or any other process?


Edit: It seems that the page was updated in the last 5 minutes. It is official the release RU2. So, How to obtain it and update from 12.1 RU1 MP1 to RU2?

Nov 12, 2012 12:38 AM

waiting here as well guys....

Nov 11, 2012 09:47 PM

one week to go.. :-o

Nov 09, 2012 03:31 AM

SEP 12.1 RU2 will release with Product notes till Nov 17 2012.

Nov 06, 2012 02:55 PM

When will SEP 12.1 RU2 be released?  I have seen some information that says it is coming out today, but no real confirmation.

Nov 06, 2012 05:44 AM


Direct migration to RU1 MP1 from this version is not supported. What you need to do, is first to migrate to 12.1 RU1, and then as a second step of migration - migrate to 12.1 RU1 MP1. I tried to explain the supported migration paths here:


You don't have to perform manual migration - you can do it remotely. Here are couple of usefull documents:

Upgrading or migrating to Symantec Endpoint Protection 12.1.1000 (RU1)

Upgrading or migrating to Symantec Endpoint Protection 12.1.1101 (RU1 MP1)


Additionally, if you are interested, you can see the remote installation process:



If you have further migration questions or issues - I would suggest you to open a new thread in the forum (so it can be easily followed) or open a case with Technical Support.

I hope your migration will go smoothly :)

Nov 06, 2012 12:07 AM


We have pan india support and i want to upgrade my clients from MR4 MP2 to SEP 12.1 RU1 MP1.

Is that possible? and those clients are across india though which method i can upgrade clients instead of doing manually.

Please suggest

Oct 08, 2012 07:37 PM

Yes, I hope that too as well.

Fingers crossed angel

Oct 08, 2012 01:30 AM

Hopefully the new release of SEP would be less issue for most endpoints.

Oct 08, 2012 01:09 AM

Ah ok, thanks for the calrification then.

Oct 07, 2012 11:26 PM

There is no official date for the release. You may see the Release of SEP 12.1 RU2 happening anytime this year.


Oct 07, 2012 11:15 PM


When is the nextSEP 12.1 RU2 released?

Sep 13, 2012 02:48 AM


Letest SEP version sepm SEPM 12.1 RU1 MP1

Next SEP 12.1 RU2 Official date yet not announce.


Sep 13, 2012 02:40 AM

What is the latest release of SEPM client 12.x?

There are some links in symantec whcih refers to SEP cleint 12.5, is there any client with this version? Please assist.







Sep 12, 2012 07:05 AM


sorry for the late answer. The direct upgrade from 12.1.671.xxx to 12.1.1101.xxx is not supported.

Here I explained why migrations to "MPs" are suppored only from its "RU" version:


I hope that clarifies more.

Aug 21, 2012 02:56 PM

Didn't get notice of the 12.1 RU1 update, but I did for the RU1 MP1, can i go directly from Version 12.1.671.4971  to Version 12.1.1101.401, skipping the Nov update? . Also so I need to download the full base product and inline update parts 1 and 2 to complete this upgrade along with the client updates?

Jun 02, 2012 01:58 AM

Migrating to Symantec Endpoint Protection 11.0.7200 (RU7 MP2)

Upgrading or migrating to Symantec Endpoint Protection 12.1.1101 (RU1 MP1)

SEP 12.x have more features hence you may think of upgrading to SEP 12.

What is new in Symantec Endpoint Protection 12.1?

Jun 02, 2012 01:39 AM

Migration from MR4 MP2/ RU6 MP2  to latest RU7 MP2 and SEP 12.1 RU1 MP1 is supported ???

Which one is best among two ???

Also i am having a PAN india support which take a time of 2-3 months for migrations which is handled by 4 SEPMs indiviually.

Jan 22, 2012 02:13 PM

Manager has usually the same version as client, so when next to the version is not specified - the version is for both - SEP client and SEP Manager (SEPM).

So, the last SEPM versions are:

11.x - 11.0.7101.1056

12.0.x - 12.0.1001.95

12.1.x - 12.1.1000.157

Jan 19, 2012 05:14 AM

Which is the latest manager version??


Nov 18, 2011 05:52 AM

added new release to the list (12.1.1000.157)

Oct 20, 2011 04:19 AM


Jul 07, 2011 03:15 AM

Added 12.1 to the list

Jun 29, 2011 06:47 AM

These are 2 separate products, so fixes for RU7 will not apply on SEP 12.1. However, it may happen that the issue will not be present on the SEP 12.1 because of different architecture.

Jun 27, 2011 03:18 AM

Would RU7 fixes be incorporated in SEP 12.1?

Jun 16, 2011 04:15 AM

We can expect RU7 soon - probably in July (still do not know official date)

Jun 03, 2011 10:37 AM

There is no public announcment on the date RU7 will be available. Stay tuned, as soon as it is out, I will post back here.

Jun 03, 2011 05:51 AM

When is the official release date for RU7...

May 09, 2011 05:07 AM

woh great news !!! RU7 could be very useful who all are using lower versions....:-)

Apr 07, 2011 08:17 PM

wow, many thanks for the explanation, I'll just wait until the RU7 comes up probably around june-july :-)

Apr 07, 2011 03:24 AM

The general supported migration steps I explained in this document:

General supported migration paths of Symantec Endpoint Protection Manager (SEPM)

It is not said that the migration will not work. However, the migration from MR4 to RU6 MP3 was not tested so it might cause some unknown issues. As I explained in the above document, MP is a Maintenance Patch for a certain MR or RU version, so this is like a patch for the major release.

There is RU7 release in plans (no official date yet, it should be this summer on the market). Direct migration from your version to RU7 will be supported.

I hope my explanation was clear enough.

Apr 07, 2011 12:57 AM

To All Symantec experts,

Why there is no direct upgrade from the older version into the newer version in easy way ?

eg. I have 11.0.4000.2295 and I want to keep to the latest RU6 MP3 but I have to step the ladder up one by one ? this is ridiculous for any environment larger than 50 units.

Mar 29, 2011 02:28 PM

Here you can find, in general, supported migration paths (direct migration from 11.0.6005.xxx to 11.0.6300.xxx is supported):


Mar 24, 2011 05:15 AM

Please find below URL to download


Mar 24, 2011 04:32 AM

stupid question , but where are these updates located? i m on Version: 11.0.6005

how can i go to the latest 11.0.6300.803? do you have a link that i can go read?



Mar 23, 2011 05:19 AM

is updated now. Thanks

Mar 22, 2011 02:21 PM

Please add version 11.0.6300.803 released 3/21/11 to your list.

Mar 03, 2011 09:02 AM

There is a small mistake in the first table. The RU6 MP2 PP1 is only for SEPM (not SEP client).

Mar 01, 2011 07:55 AM

Will be updated once new versions will be released
