License Auto Update fails

Cause

Any licenses obtained prior to U4 are now known as ‘Legacy Licenses’. Auto Update functionality cannot migrate a Legacy License to the new Veeam Instance License.
 
The message most likely received is:
Error    Server message: License key type is not supported at the moment.
 

Solution

Obtain a new Veeam Instance License and Auto Update will function again.
