                  system is being deprecated      License Central to update
                  and will be unavailable in      your license.

 

Cause

Starting with DDOS 8.6.x and subsequent releases, support for legacy licensing formats (.lic and .xml) is being phased out as Dell Dynamic Licensing (DL) becomes the preferred licensing model.

Resolution

This pre-upgrade check generates a warning only and does not prevent the upgrade from proceeding. The upgrade can continue and is expected to complete successfully.

 

After completing the upgrade to a version that supports Dynamic Licensing, customers are encouraged to migrate their existing licensing configuration to the Dynamic Licensing.
 
The procedure is outlined below-

From the Data Domain UI, navigate to Administration > Licenses, and then select the "Add Dynamic License" option from the right pane.




Option 1 - 
The Dell Software Licensing Central (SLC) option is recommended for systems connected through Dell Connectivity Services or a Secure Connect Gateway (SCG).





Click on Apply button and Verify that the message "The license was applied successfully" is displayed.

 
Option 2 -
 
Select License Type "Offline Registration File" and hit the Upload button to browse and select .dl file. and click on apply. 
 
Verify that the message "The license was applied successfully" is displayed and that the license details are visible on the Licenses page.
