Import ESXi images to create upgrade baselines, which you can use to upgrade hosts in your vSphere inventory.

  • Required privileges: VMware vSphere Update Manager.Upload File.

You can use ESXi .iso images to upgrade ESXi 6.0.x hosts and ESXi 6.5.x hosts to ESXi 6.7.

To upgrade hosts, use the ESXi installer image distributed by VMware with the name format VMware-VMvisor-Installer-6.7.0-build_number.x86_64.iso or a custom image created by using vSphere ESXi Image Builder.


  1. In the vSphere Client, select Menu > Update Manager.
  2. Navigate to Menu > Update Manager.
    The Update Manager home appears.
  3. On the ESXi Images tab, click Import.
    The Import ESXi Image dialog box opens.
  4. To import an image from your local system, click the Browse button and locate the ESXi image that you want to upload.
    Local images are imported immediately.
  5. (Optional) To import an image from a URL , enter the address in the Image text box and click Import and wait for the upload progress of the ESXi image to finish.


The ISO image that you uploaded appears in the list of images. You can view information about the ESXi image, such as product, version, and build details, vendor, acceptance level, and creation date.
