You can upgrade all available templates from an ESXi host or upload new templates for AppStacks and Writable Volumes.
Important: If you have upgraded
App Volumes from an earlier version, you must upload the prepackaged templates again manually. You cannot upgrade the templates by copying them directly to the storage location as the location is locked by
App Volumes Manager to prevent accidental deletion of volumes. However, any user-defined custom templates are automatically carried over, and you do not have to upload them again.
If you choose to install a new App Volumes 4 App Volumes Manager, you must perform the steps as described in this section.
