 * Applying Azure network security groups on the private link subnet to Azure Key Vault isn't supported for Azure NetApp Files customer-managed keys. Network security groups don't affect connectivity to Private Link unless `Private endpoint network policy` is enabled on the subnet. It's _required_ to keep this option disabled.
 * If Azure NetApp Files fails to create a customer-managed key volume, error messages are displayed. Refer to the [Error messages and troubleshooting](#error-messages-and-troubleshooting) section for more information.
 * Do not make any changes to the underlying Azure Key Vault or Azure Private Endpoint after creating a customer-managed keys volume. Making changes can make the volumes inaccessible.

+* Azure NetApp Files supports the ability to [transition existing volumes from platform-managed keys (PMK) to customer-managed keys (CMK) without data migration](#transition-volumes). This provides you flexibility of encryption key lifecycle (renewals, rotations) and extra security for regulated industry requirements.
 * If Azure Key Vault becomes inaccessible, Azure NetApp Files loses its access to the encryption keys and the ability to read or write data to volumes enabled with customer-managed keys. In this situation, create a support ticket to have access manually restored for the affected volumes.
 * Azure NetApp Files supports customer-managed keys on source and data replication volumes with cross-region replication or cross-zone replication relationships.
