Transform the data extract¶
Once you have extracted the data from your MSR 2.9.x system, you must transform the metadata into a format that is suitable for migration to an MSR 3.0 system.
To transform the data extract, run the following command on the target MSR 3.0.x system:
docker run \
--rm -it \
-v $HOME/.kube/config:/.kube/config \
-v <local-migration-directory>:/migration:Z \
-e KUBECONFIG='/.kube/config' \
registry.mirantis.com/msr/mmt:<mmt-version> \
transform metadata msr \
--storage-mode <inplace|copy> \
/migration
Important
The Kubernetes context for the MSR 3.0 system must be present in
$HOME/.kube/config
or it must be explicitly passed to MMT, using the
following option:
-v /path/to/context/kube.yml:/.kube/config/kube.yml
