You can upgrade the Migration Toolkit for Containers (MTC) on OKD 4.16 by using the Operator Lifecycle Manager.
When upgrading the MTC by using the Operator Lifecycle Manager, you must use a supported migration path. |
Migrating from OKD 3 to OKD 4 requires a legacy MTC Operator and MTC 1.7.x.
Migrating from MTC 1.7.x to MTC 1.8.x is not supported.
You must use MTC 1.7.x to migrate anything with a source of OKD 4.9 or earlier.
MTC 1.7.x must be used on both source and destination.
MTC 1.8.x only supports migrations from OKD 4.10 or later to OKD 4.10 or later. For migrations only involving cluster versions 4.10 and later, either 1.7.x or 1.8.x may be used. However, it must be the same MTC version on both source & destination.
Migration from source MTC 1.7.x to destination MTC 1.8.x is unsupported.
Migration from source MTC 1.8.x to destination MTC 1.7.x is unsupported.

You can upgrade Migration Toolkit for Containers (MTC) on OKD 3 by manually installing the legacy Migration Toolkit for Containers Operator.
You must be logged in as a user with cluster-admin
privileges.
You must have access to registry.redhat.io
.
You must have podman
installed.
Log in to registry.redhat.io
with your Red Hat Customer Portal credentials by entering the following command:
$ podman login registry.redhat.io
Download the operator.yml
file by entering the following command:
$ podman cp $(podman create \
registry.redhat.io/rhmtc/openshift-migration-legacy-rhel8-operator:v1.8):/operator.yml ./
Replace the Migration Toolkit for Containers Operator by entering the following command:
$ oc replace --force -f operator.yml
Scale the migration-operator
deployment to 0
to stop the deployment by entering the following command:
$ oc scale -n openshift-migration --replicas=0 deployment/migration-operator
Scale the migration-operator
deployment to 1
to start the deployment and apply the changes by entering the following command:
$ oc scale -n openshift-migration --replicas=1 deployment/migration-operator
Verify that the migration-operator
was upgraded by entering the following command:
$ oc -o yaml -n openshift-migration get deployment/migration-operator | grep image: | awk -F ":" '{ print $NF }'
Download the controller.yml
file by entering the following command:
$ podman cp $(podman create \
registry.redhat.io/rhmtc/openshift-migration-legacy-rhel8-operator:v1.8):/controller.yml ./
Create the migration-controller
object by entering the following command:
$ oc create -f controller.yml
If you have previously added the OKD 3 cluster to the MTC web console, you must update the service account token in the web console because the upgrade process deletes and restores the openshift-migration
namespace:
Obtain the service account token by entering the following command:
$ oc sa get-token migration-controller -n openshift-migration
In the MTC web console, click Clusters.
Click the Options menu next to the cluster and select Edit.
Enter the new service account token in the Service account token field.
Click Update cluster and then click Close.
Verify that the MTC pods are running by entering the following command:
$ oc get pods -n openshift-migration
If you are upgrading Migration Toolkit for Containers (MTC) version 1.3.x to 1.8, you must update the MigPlan
custom resource (CR) manifest on the cluster on which the MigrationController
pod is running.
Because the indirectImageMigration
and indirectVolumeMigration
parameters do not exist in MTC 1.3, their default value in version 1.4 is false
, which means that direct image migration and direct volume migration are enabled. Because the direct migration requirements are not fulfilled, the migration plan cannot reach a Ready
state unless these parameter values are changed to true
.

Get the MigPlan
CR manifest:

Update the following parameter values and save the file as migplan.yaml
:
...
spec:
indirectImageMigration: true
indirectVolumeMigration: true
Replace the MigPlan
CR manifest to apply the changes:
$ oc replace -f migplan.yaml -n openshift-migration
Get the updated MigPlan
CR manifest to verify the changes:
$ oc get migplan <migplan> -o yaml -n openshift-migration
