Updating to ESXi 7.0 Update 3f

There are three ways to update to ESXi 7.0 Update 3f. These include the following:

  • Use the esxcli command line
  • Use Update Manager
  • Use vSphere Lifecycle Manager image-based update

One of the easiest ways, especially for home lab enthusiasts is to update your ESXi server using the command line. If you are not running a vSphere cluster in your lab environment or just running a single node, you will want to upgrade your host using the command line instead of the other options that require a vSphere cluster.

The command to use the esxcli command from the shell to upgrade to 7.0 U3f is as follows:

esxcli software profile update -p ESXi-7.0U3f-20036589-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml
