How to upgrade ESXi 6.0 to ESXi 6.5 using VMware Update Manager

In the last post about upgrading ESXi 6.0 to ESXi 6.5, I showed you How to upgrade ESXi 6.0 to ESXi 6.5 using esxcli and How to upgrade ESXi 6.0 to ESXi 6.5 using Interactive Installer. In this post, I will show you how to upgrade ESXi 6.0 to ESXi 6.5 using VMware Update Manager.

In my previous post, I showed you the process of Migration of Windows vCenter Server 6.x to vCenter Server 6.5 Appliance. With the release of vSphere 6.5, vCenter Server Appliance finally has built-in Update Manager. This means that in 99% cases Windows Server is no longer needed to manage updates of ESXi and virtual appliances.

Prerequisites

Import ESXi ISO to VMware Update Manager

  1. Log in to vSphere Web Client and click Update Manager.
  2. Choose your vCenter Server and click Manage.
  3. Click ESXi Images.
