In the Release 1 cluster, access the operator node and use the olcnectl module backup command to back up the Kubernetes Module in the environment. Use the syntax:

olcnectl module backup \
--environment-name environment_name \
--name cluster_name

For example:

olcnectl module backup \
--environment-name myenvironment \
--name mycluster

For more information on backing up a Release 1 cluster, see Oracle Cloud Native Environment: Kubernetes Module for Release 1.9.
