To update the Axxon One license, do the following:

1. Deactivate the installed license (see Deactivating a license in Linux OS). 
2. Create an activation request (see Creating an activation request in Linux OS). Proceed with payment.
   

   Skip this step if you want to activate already purchased system features.

3. Activate your purchased license (see Activation by applying a license file in Linux OS, Activation with a serial number in Linux OS).

As a result, the Axxon One license is updated.
