Export license keys that are already loaded in your system

Export license keys that are already loaded in your system

Every now and then, there is a need to export license keys from a system.  I needed to get into the VAR layer to modify code in a Microsoft VPC, but as we all know, Contoso license keys don't come with the BUS/CUS/VAR access codes.  So I did what any developer would do:

• Write a job to export the Contoso license key file
• Import my company's partner license key file
• DO NOT SYNC when it asks
• Jump in the VAR layer using our layer access code to make my changes real quick
• Import back the Contoso license key file I exported from my job and SYNC
