Our Present VMware Infrastructure : Presently we are managing our infrastructure by using one Virtual Center Server (2.5) standard for all our ESX 3.5 Ent Servers which are placed in different security zones.

Our Proposed Infrastructure : We have received required vSphere 4 Ent licenses alongwith required vCenter Server 4 Standard upgraded licenses.

We would like to know the step by step plan for the folloiwng :

1. How to upgrade our present Virtual Center Server Standard (2.5) to vCenter Server 4 Standard.

2. How to upgrade our present ESX 3.5 Ent Server to vSphere 4 Ent Server.

3. What are the methods we should maintain for the licenses.

If somebody can provide the required step by step document to me (anindya.ghoshal@itc.in) if possible.
