We're planning to upgrade agent from 4.5 to 4.6 p1. We've EPO 4.5.We're using Microsoft technologies. Servers are Win2k3 SP2, Win2k8 and Win2k8 R2, WinXP professional with sp3.
Could anyone please brief me about the extension files required to upgrade the agent?
And do I need to take backup (and how to take it) of the policies before installing the new extensions?
Are there any chances of corruption of existing policies after installing the new extensions?
Can I roll back the agent to previous version i.e. to 4.5 in case of any issues? and do I need to uninstall the extension files which are newly installed?
Thanks in advance.
