Avi Load Balancer Controller enforces feature restrictions for each edition. Therefore, the configuration needs to adhere to Essentials Edition for allowing the transition from Enterprise Edition to Essentials Edition.

The following is the sample output for the configuration audit command when the target tier is set as essentials. The following output exhibits the configurations and features which are not supported in the Essentials Edition. Take the required actions as per the output of the configuration output command and then change the license tier edition.

The following are the additional points to check while changing the licensing tier from the Enterprise edition to the Essentials edition:

  • Save the backup configuration before changing the licensing edition.

  • Ensure that the base versions of Avi Load Balancer Controllers and Avi Load Balancer SEs are same.

    Note:

    Controllers and SEs can run on different patch versions.

Prerequisites

A config audit tool is introduced to check the configurations that are not supported for the target edition. Run the config audit tool to check the violations in the configurations. Resolve all the violations before proceeding to change from the Enterprise Edition to the Essentials edition. The configuration audit API performs licensing checks on all the objects in the system and reports various violations. It ignores the violations in system default objects as they are handled internally.

Use the following Avi Load Balancer CLI or the REST API to check the unsupported configuration and take the required actions.

  • Avi Load Balancer CLI: show configuration audit tier <tier_name>

  • Avi Load Balancer REST API: /api/config-audit/tier/ <tier_name>
