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