### Can I use self-signed certificates? <a href="#can-i-use-self-signed-certificates" id="can-i-use-self-signed-certificates"></a>

Yes. There are additional steps that you must take to configure self-signed certificates. For more information, go to [Use self-signed certificates](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-installationupgrade/helm-installation/install-using-helm.md#use-self-signed-certificates-with-helm-based-installations).

### How do I manage feature flags? <a href="#how-do-i-manage-feature-flags" id="how-do-i-manage-feature-flags"></a>

You update Feature Flags using the `override.yaml` file for the Helm chart of your base installation. You can also update the `values.yaml` file for your Kubernetes delegate. For more information, go to [Manage Feature Flags](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-installationupgrade/helm-installation/manage-feature-flags.md).

### Can I install Harness Self-Managed Enterprise Edition in an air-gapped environment? <a href="#can-i-install-harness-self-managed-enterprise-edition-in-an-air-gapped-environment" id="can-i-install-harness-self-managed-enterprise-edition-in-an-air-gapped-environment"></a>

Yes. For more information, go to [Install in an air-gapped environment](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/smp-installationupgrade/helm-installation/install-in-an-air-gapped-environment.md).

### How can I upgrade volumes created during Helm installation from gp2 to gp3? <a href="#how-can-i-upgrade-volumes-created-during-helm-installation-from-gp2-to-gp3" id="how-can-i-upgrade-volumes-created-during-helm-installation-from-gp2-to-gp3"></a>

Harness does not control volume types. Storage classes control volume types. You can modify the storage class setting, but you might lose data if AWS does not support a direct upgrade from `gp2` to `gp3`. Go to [Storage classes - AWS EBS](https://kubernetes.io/docs/concepts/storage/storage-classes/#aws-ebs) to understand Amazon Elastic Block Store (EBS) storage classes.

### Can I use external secrets for license values? <a href="#can-i-use-external-secrets-for-license-values" id="can-i-use-external-secrets-for-license-values"></a>

Yes, you can use Kubernetes-based external secrets for Harness Self-Managed Enterprise Edition license values in your Helm charts. For more information, go to [Use external secrets for license values](/self-managed-enterprise-edition/use-self-managed-enterprise-edition/advanced-configuration/use-external-secrets-for-license-values.md).

### How can I troubleshoot installation failures? <a href="#how-can-i-troubleshoot-installation-failures" id="how-can-i-troubleshoot-installation-failures"></a>

For installation troubleshooting, go to [Helm installation failure](/self-managed-enterprise-edition/troubleshooting-and-resources/troubleshooting/helm-install-failure.md).
