I need to upgrade my ESX 3.5 environment. First I am thinking vCenter. I have 2.5 version with 147633 build. Full blown SQL 2005.
What are the procedures doing that? I cannot find the correct documentation on that.
Can I go directly from 3.5 to 4.1? or 4.0 first?
Will it affect the hosts in any way? Do I need to reboot? I am thinking to make a SAN snapshot prior to upgrade.
