This document describes the license mechanism and expected behavior when a trial license expires.
If during set up of your appliance, you selected the 30-day trial license and missed the expiry date, you can simply navigate to the 'License' tab and generate a license request.
Send the license file to firstname.lastname@example.org. A permanent license will be returned within 72 hours.
Your license will revert to the Free Edition and you can continue using the appliance as normal. However, some features such as jobs and remote node configuration will be restricted.
Once the permanent license is applied however, these features will once again become available.
