When you adjust the license between devices or want to change the license when the original license is incompatible on the upgraded device, run the license revoke command to revoke the existing license. The system then returns a license revocation code. You can use the license revocation code to apply for a new license file, and activate the new license file to the device during the trial period.
NOTICE:
Running the license revoke command causes the license file to be in trial state. The trial period is 60 days. If the trial period is reached, services will be interrupted. Exercise caution when you run the license revoke command.
1. Before running the license revoke command, perform the following operations:
1). Contact agents and determine whether the license can be replaced. Check the time the license file can be obtained.
2). Contact Huawei technical support personnel.
