I need to update our vmware esxi servers from 4.1u1 to the latest 4.1 versions.
I asked the question how to do it in another thread and according to the answer of the experts, the procedures that I need to follow is :
1. update vcenter to the latest 4.1 version on primary site
2.update srm to the latest 4.1 version on primary site
3.update vcenter to the latest 4.1 version on dr site
4.update srm to the latest 4.1 version on dr site
5. install update manager on primary site
6. install update manager on dr site
7. patch esxi servers to the latest 4.1 version
8 upgrade vmware tools to the latest version on guest OS
Now my managers wants from me to provide a backout plan(roll back plan), in case of any problem, how to roll back everything to the initial point.
Could you help me what should I put in this plan, and how it should look like. Maybe anything from your experience if you were requested to provide a such plan, or something that you are using.
