The existing clients can stay on the existing version that they are on. There is not a rush to upgrade them after the core server is upgraded. In terms of the way to upgrade them, in the patch manager there will be a SP2 patch that you can push out to those systems to upgrade them. You may need to download LANDesk application patches after the upgrade to see the SP's
I would like to clarify what Eric says about there not being a rush to update the clients....
There is not urgent need, but in my opinion you will want to install the SP2 patch on your clients in a reasonable amount of time.
After you install SP2 on your core you should strongly consider installing the patches listed here:
http://community.landesk.com/support/docs/DOC-22561 on your core and then read the info at that link about how to then patch your clients.
There are a number of issues in SP2 that these resolve.
The nice thing is, you do not need to push out new agents, but can patch them instead.
If after applying these patches to the core, if I then create a new agent and install it would it be fully patched or would I still need to apply the patches to the agent?
Yes, you could apply all updates to the core and then be sure to click on the "rebuild all" icon in the tool bar. Then if you push a new agent out that should do it.
Historically we and many other have had issues with agent re-installations, some would fail, others would appear to succeed but we would notice later on that vulscans or other actions were not working... therefor we now avoid agent re-installations when possible.
If you decide to do this, I also suggest you give your agent name a version or date... such as "PC Agent v2" or "PC Agent 2011-10-18"
This makes it easy to query systems to make sure they have your current agent
We usually use the Advance Agent deployed via AD group policy. It seems to do a good job of uninstalling and reinstalling the agent.
I agree with the naming of the agents. Very useful.
Thank you for your help!
