Add a License to a Project
If you just bought a license and want to apply your license to a project that is showing the red trial banner, then this section is for you.
In case you don’t have a license but instead quota upgrades via a subscription (older mechanism), then adjust the project quotas directly.
To apply a license to a project
Open the project and click “Settings” (wrench icon).
Scroll down to the Licenses section.
Click the button marked “Upgrade using a license key…”.
Enter your license key in the box that opens and click Save.
Then start or restart the project in order to activate the license.
