Upgrade ESXI 5.1 to 6.5

This post was originally published on this site

Hi all,


We are using a HP Branded VMWare ESXI 5.1 hypervisor on a HP Proliant ML350P Gen8. We do not use Vcenter and we only have one host. We want to upgrade to ESXI 6.5. I have been Googling to answer some of my questions but cant find some of the answers. Maybe you can help me out…


1. I have found that I cant upgrade from 5.1 –> 6.1. The installer only can install 6.5 and preserve the datastores. In what steps can I upgrade? 5.1 –> 5.5 and then 6.5 or?

2. I cant find if the hardware is compatible with ESXI 6.5 but the server isn’t listed for 5.1 either so I dont know if i can upgrade?


Thx for your help.
