I'm running VMware ESXi servers 5.1 Update 2 and Update 1 managed by my Windows VMware VCenter VM is currently on version vCenter Server 5.1 Update 1 (build 1064983 2013-04-25) as follows:
Windows Server 2008 R2 SP1 Standard - 10 GB vRAM
Microsoft SQL Server 2008 Standard Edition (64-bit) (SP2) - 10.0.4000.0
all in one virtual machine.
Which VCenter server inline upgrade is the easiest without having to bother with SSO or some other java problem ?
