Prerequisites

Community Edition: Apply for the new license code at https://www.iomesh.com/license.
Enterprise Edition: Contact SmartX sales for the new license code.

Procedure

Delete the old Kubernetes Secret and the spec.licenseSecretName field in iomesh object.

kubectl delete secret iomesh-authorization-code -n iomesh-system

kubectl edit iomesh -n iomesh-system

spec:
  licenseSecretName: iomesh-authorization-code # Delete this line.

Create a file license-code.txt and save the new license code in it.

Create a Kubernetes Secret.

kubectl create secret generic iomesh-authorization-code -n iomesh-system --from-file=authorizationCode=./license-code.txt

Add the field spec.licenseSecretName . Fill in the value iomesh-authorization-code, which is the Kubernetes Secret name created above.
```
kubectl edit iomesh -n iomesh-system
```
```
spec:
  licenseSecretName: iomesh-authorization-code
```
Confirm the update, and whether the update is successful will be shown in events.
```
kubectl describe iomesh -n iomesh-system # Whether the update is successful will be displayed in the events.
```
If the update fails, verify if you have entered the correct license code. If it still does not work, reset the field spec.licenseSecretName.

Verify that the license expiration date and other details are as expected.

kubectl get iomesh -n iomesh-system -o=jsonpath='{.items[0].status.license}'
