Upgrading the MTC Operator on an OpenShift Container Platform 3 cluster

You can upgrade MTC on an OpenShift Container Platform 3 cluster by downloading the latest operator.yml file and replacing the existing MTC Operator.

If you remove and recreate the namespace, you must update the cluster’s service account token in the MTC web console.
Procedure

  1. Log in to registry.redhat.io with your Red Hat Customer Portal credentials:

    $ sudo podman login registry.redhat.io

  2. Download the latest operator.yml file:

    $ sudo podman cp $(sudo podman create registry.redhat.io/rhmtc/openshift-migration-rhel7-operator:v1.3.0):/operator.yml ./

  3. Replace the MTC Operator:

    $ oc replace --force -f operator.yml

  4. If you are upgrading from version 1.1.2 or earlier, delete the Restic Pod to apply the changes:

    1. Get the Restic Pod name:

      $ oc get pod -n openshift-migration | grep restic

    2. Delete the Restic Pod or Pods:

      $ oc delete pod <restic_pod>

  5. If you are upgrading from version 1.2 or later, scale the migration-operator deployment to apply the changes:

    1. Scale the migration-operator deployment to 0:

      $ oc scale -n openshift-migration --replicas=0 deployment/migration-operator

    2. Scale the migration-operator deployment to 1 to apply the changes:

      $ oc scale -n openshift-migration --replicas=1 deployment/migration-operator

  6. Verify that the operator was upgraded to the latest version:

    $ oc -o yaml -n openshift-migration get deployment/migration-operator | grep image: | awk -F ":" '{ print $NF }'
