Upgrading to a model that requires no additional virtual hardware
When the existing virtual hardware is sufficient for the target model you want to run, you only need a license for the new model. The appliance specification description includes the potential bandwidth and connection counts. The current specification appears in bold. You might see specifications listed but grayed out. After the license or required hardware for a specification is installed, it become available.
1. Stop the acceleration service.
2. Choose Administration > Maintenance: Licenses to display the Licenses page.
3. The appliance specifications appear at the bottom of the page.
4. Select the hardware specification that you want to activate, apply it, and then restart the service.
