one customer has a very old vmware environment.
All hosts have version esx 3.5.
One host has now errors.
I want to upgrade to latest version of vshere5.5.
Can you tell me the steps, how to upgrade from 3.5 to 5.5 ?
Yet I have just license for 3.5 not 4 or 5 or 5.5.
But I think I can upgrade to the higher version within the evaluation period, right ?
