SEP version upgrade: is it possible to use existing content/definitions?

I've to upgrade a client, let me say, from version 12.1 RU1 to 12.1 RU2.

The client already has, onboard, latest definitions.

If I use a package with only basic content for the installation, will the client use the existing definitions or it will download a new full package?
I'd like to know if with a version change we can only deploy the "light" package instead of the heavy one (if target clients already have definitions).

I hope this could be possible since the definitions sets are the same for different versions.

The client will detect what update it currently has. If it is older than what is in the package, the package should update it accordingly with what the content it contains. If it were newer, it would just use what it currently already has.

So in your case, it already has latest defs. It will use those and no updates will be needed.

With SEP 12.1 it will always use the latest definiton what your manager has when you push the package.

use the light package for the install.

Hi,

If upgrading from SEP 11.x to SEP 12.1 will contain full package but upgrading from SEP 12.1 RU1 to SEP 12.1 RU2 will contain delta updates only.

Hello,

To Answer your Question, when SEP version 12.1 clients are deployed with Packages from SEPM, these packages are created with Latest definitions in it.

NOTE: The packages would have updated definitions only when the SEPM had latest definitions on them during the package creation.

So as soon as SEP clients gets installed, the clients are installed with latest definitions.

Now, incase, these clients are Mobile machines, and then connect to the SEPM for definitions however, say incase, they are unable to fetch the entire downloads, then the next time it downloads it would download the same definitions again. 

It would fetch those days definitions which have not been received by Clients.

Hi Mithun,

thanks for your answer but my question was a little bit different.

I was asking if, with a new package with no definitions (basic content creation), the client will use the existing definition related to the previous existing version.

Based on my experience, yes, it will.

Hello,

In case of a new Basic content package of SEP 12.1 with no definitions is deployed on the SEP 11.x client, the SEP 12.1 client upon installation would not have any definitions.

Secondly, it would download the Latest Definitions from the SEPM 12.1 as soon as it gets installed and would not use the older version of SEP 11.x Definitions.

The Reason is that SEP 12.1 Architecture is different than of SEP 11.x.

However, in case you have older version is SEP 12.1 RU1 or below and you are deploying package of SEP 12.1 RU2 then it would use the older definitions of SEP 12.1 RU1 which are already on the client machine.

Hope that helps!!

During installation , the virus defs folder will be replaced by the virusdef.zip file

if this file is not present in the installation folder, there wont be any overrite and it will still have the old definitions
