This topic provides information on the available upgrade, downgrade and uninstall options for JCNR.
Upgrade from Cloud-Native Router Release 23.4 and Earlier
Upgrading to this release from Cloud-Native Router release 23.4 and earlier is not supported. You must uninstall your existing Cloud-Native Router release before you can install this Cloud-Native Router release. We show you how to do this below.
Starting with Cloud-Native Router release 23.2, the Cloud-Native Router license format has changed. Request a new license key from the JAL portal if your existing Cloud-Native Router release is earlier than release 23.2.
Upgrade from Cloud-Native Router Release 24.2 and Later
Downgrade/Rollback JCNR
To downgrade or roll back from the current version to an older or previous version, uninstall the current version and install the older or previous version.
Uninstall JCNR
Uninstalling Cloud-Native Router restores interfaces to their original state by
unbinding from DPDK and binding back to the original driver. It also deletes
contents of Cloud-Native Router directories, deletes cRPD created interfaces and
removes any Kubernetes objects created for JCNR. (See the
restoreInterfaces
attribute in the Helm chart.)
Uninstalling Cloud-Native Router using Helm does not delete the
jcnr
namespace or the jcnr-secrets
.
Delete these manually if needed.
