That cmdlet basically puts the software into a staging area which does nothing until an administrator either approves or cancels the pending update.
The Approved Version is exactly as it sounds: the version of software which the administrator has most recently approved for a given device mode.
The Restore Version is initially blank and will be populated when this process is performed again with another newer update.
As important as upgrading the firmware is, having a way to reverse the update is just as imperative.
It is always possible that a new firmware version does not operate as expected in some environments so if an issue is discovered soon after upgrading to a new version then being able to roll-back the devices to the previous release is critical.
