How to update the Windows Agent correctly?

Question

Hi, i have this situation

Server version 2.11.1

User agent :OCS-NG_WINDOWS_AGENT_v2.9.2.0

and i want to upgrade the agent software but i can't find an official tutorial. On issue page on github there is a open issue for the downloader that remain on older version.

Someone have some instruction?

Thanks

Answer 1

You have informations on documentation with some ways to install : GPO, Packager, .exe plus script ...

You have indication about Packager which is NOT designed for upgrade ...

The .exe (and script) had a switch '/upgrade'  well designed for this usage ...

(A VERY BAD way is to remove and install new agent due the risk of change deviceid !!)

Answer 2

The exe script no longer has the option '/upgrade'

Answer 3

NO, I write my own script WITH /upgrade ...

(There is NO standard script, you need to create your own script !)

Answer 4

sorry i don't understand if you write you own script why you use the option '/upgrade'?

I think that the upgrade of the agent must be simple and well documented

Answer 5

I explain the problem of upgrading in older thread ... (you could find it easily)

You don't understand there is a problem of (windows) service when you upgrade changing the .exe file providing service, so that is the reason of switch '/upgrade'.

Write your own scripts of installation and/or upgrade is an efficiant way when managing hundreds of PC ...

Answer 6

launch with pstools

PsExec.exe \\[PC] -c -f -s C:\Scripts\ocs-agent-update\install.bat

Install.bat :

---

powershell -executionpolicy bypass -noprofile -command "&{ \\servershare\OCS_Inventory\install.ps1}"

powershell script : install.ps1
