I am currently planning to upgrade from 3.5 to 4.1 . I made a plan but i need somebody to check this give his opinion , still can be something i missed and i don't want to ruin environment.
So here is my plan.
I prepared VCenter 4.1 and a host with Vsphere 4.1
I have 4 hosts ESX 3.5.
- made old vcenter as license server until i clean install from vc 4.1
During the weekend i will remove ESX 3.5 from old vcenter and i will add to new Vcenter 4.1
There will be :
- ESX 4.1 host5
- ESX 3.5 host1
- ESX 3.5 host2
- ESX 3.5 host3
- ESX 3.5 host4
Then i clean install one by one.
Is this ok ?
