Explanation: Detailed Description
Exports an Image Profile object as either an ESXi ISO image that can be booted up and used as an ESXi installer, or an offline depot ZIP file that contains metadata plus the VIB packages. In both cases, downloads the VIB binaries and validates the VIB signatures.
You can perform the following tasks with the offline depot ZIP file:
*Import the ZIP into VMware Update Manager for patch remediation
*Download the ZIP to an ESXi host and used with esxcli for installation
*Re-import the ZIP into ImageBuilder itself using Add-EsxSoftwareDepot
You can specify either -ExportToIso or -ExportToBundle but not both.
