Upgrading to NetBackup 10.3 and cluster environment
In the cluster environments such as Azure Kubernetes Service (AKS), Amazon Elastic Kubernetes Service (EKS), and NetBackup Flex Scale, you are required to migrate cloud volume-associated credentials to add the new engines in NetBackup 10.3 or later.
See the Migrating or upgrading MSDP Cloud and CMS topic in the NetBackup Web UI Administration's Guide to save the cloud credentials in CMS and establish the associate credentials with the existing cloud volumes.
