Select the storage mode¶
Once the prerequisites are met, you can select
from two available storage modes for migrating binary image data from an MSR
2.9.x system to an MSR 3.0.x system:
In all but one stage of the migration workflow, you will indicate the
storage mode of choice in the
storage-mode parameter setting. The step
in which you do not indicate the storage mode is
Restore the data extract.
The binary image data remains in its original location, leaving the MSR 3.0.x system to connect to the MSR 2.9.x storage location.
Due to its ability to handle large amounts of data, Mirantis
recommends the use of
The binary image data is copied from the source system to a local directory on the workstation that is running MMT. This mode allows movement from one storage location to another. It is especially useful in air-gapped environments.
Migrations from source MSR 2.9.x systems that use Docker volumes for image
storage, such as local filesystem storage back end, can only be performed
copy storage mode. Refer to
Filesystem storage back ends for more information.
