Upgrade from SEP 12.1.1 RU1 to SEP 12.1.3

Created: 23 Sep 2013 | 7 comments


We just needed some guidance on upgrading our SEP Manager from SEP 12.1.1 RU1 to SEP 12.1.3

Please advice if it's better to upgrade the existing 12.1.1 or to install on another server.

I also want to have one management server for both office rather than separate ones as it is now.

to upgrade your SEPM to RU3, please follow standard migration procedure:

In few words, take a backup of your current SEPM, drop the new SEPM installation package into that same server, run the setup.exe and just follow the wizard.

To decomission one isolated SEPM (B) and have all clients managed by a single SEPM (A) you need to connect B's clients to A.

Once you have migrated A, in the new SEPM you will find a new feature to reset the communication settings in your clients (those you want to move from B to A), read more here:

Once those clients have been moved to A, you may switch B off.

Remember to use the GUPs in locations which are remote to the SEPM:

Thank you for posting in Symantec community.

I would be glad to answer your query.

You can do an upgrade with the help of this article, it should be similar in your case as well.

Upgrade process from SEP 12.1 RU1 MP1 to SEP 12.1 RU2

A majority of small and medium-sized organizations need only a single site to centrally manage network security. Since each site has only one database, all data is centrally located.

Even a large organization with a single geographic location and fewer than 45-50,000 clients typically only needs one site. But for the organizations that are too complex to manage centrally, you should use a distributed management architecture with multiple sites.

You should consider multiple sites for any of the following factors:

  • A large number of clients.

  • The number of geographical locations and the type of communications links between them.

  • The number of functional divisions or administrative groups.

  • The number of datacenters. A best practice is to set up one Symantec Endpoint Protection site for each datacenter.

  • How frequently you want to update the content.

  • How much client log data you need to retain, how long you need to retain it, and where it should be stored.

  • A slow WAN link between two physical locations. If you set up a second site with its own management server, you can minimize the client-server traffic over that slow link.

  • Any miscellaneous corporate management and IT security management considerations that are unique.

Use the following size guidelines to decide how many sites to install:

  • Install as few sites as possible, up to a maximum of 20 sites.

  • Connect up to 10 management servers to a database.

  • Connect up to 50,000 clients to a management server.

If depends upon the number of clients you are going to manage

You can upgrade simply the existing server not to create a new one.

First upgrade the management server after that schedule the client with autoupgrade feature.

Remote clients you can upgrade with remote client.exe(deployment wizard)

To manage the remote site clients you can use GUP feature.
