Hi All,
In Our Organisation we have single server environment, all the Hardware is of IBM 3650M3. These server contains 8 HDD configured in 2*146 = Raid 1, 3*500 = Raid 5.
On these server we have installed ESXi 4.1 two years ago, now our management had asked to upgrade all these server to latest 5.1.
In our setup we have vCenter server which is Virtual machine on the same Host, along with 3 Different Virtual machines.
Can you please guide us, how to perfrom single server upgrade?
Our Intial Plan is
1. To create a new VM for 5.1 and installed vCenter
2. Mount the ISO file and install the 5.1 on host.
Not sure if this is the safe approach, as we have to minimise the downtime.
Thanks
