vCenter Server Appliance upgrade from 5.5 to 6.0

Hi All,

Today we will discuss about how to upgrade an existing vCenter 5.5 appliance to vCenter 6.0 appliance.

I am using two ESXi servers with 4VPUs and 12GB RAM.

Pre checks:-

  1. Active snapshot of your vcsa5.5.
  2. Source ESXi and destination ESXi health status.
  3. SSL certificate validation.
  4. Port 22 and 443 should be open in the firewall.
  5. Sufficient storage.
  6. Database backup and comparability  if you are using external database.
  7. Network redundancy.
  8. Client Integration Plug-in in your windows host.
  9. Refer Upgrading to vCenter Server 6.0 best practices  KB2109772
  10. VCSA 6.0 iso Image.

In the below screen shot you can  find my existing vCenter appliance with vcsa5.5 on esxi1.vclass.local host.

I am log-in in to the vcsa5.5 web client.
