Endpoint Protection

Recently we upgraded our SEPM server from 12.1.6 MR1 to 12.1.6 MR4. All process compleated without any error. 

Before upgrade the entire group clients i have selected a small group of client for test. But its not updated to latest version. 

I have followed exactly the same procedure mentioned in the below link. Please advise.

can you check the SEP_Inst.log file on the client side? Have you made sure that you have assigned both 32 bit and 64 bit packages to the group? Whats the heartbeat interval set to?

Tnx Rafeeq for your prompt reply. Yes I assigned both 32 and 64 bit packages to the group. and heartbeat interval of the group is 1 hour.

What do you see under [right click on client] > Edit Properties > General > Deployment status? Is there an error message?

If your clients are in pull modus, it may take up to 1 hour until they will recognize the new version. And there could be an update schedule (see Clients > [Group] > Install Packages > Edit Client Install Package Properties) that can add even more time until the deployment will start.

Deployment Status: The client is requesting the full version of the upgrade package due to the delta's failure

Deployment Message: Client has failed to apply upgrade package, type SymDelta version 12.1.6867.6400 filesize 4650242. Setting to get full version of the package.
