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: inplace
and copy
.
Note
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. The MSR 3.0.x system must be configured to use the same external storage as the 2.9.x system. Refer to configure-external-storage for more information. Important 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. |
Important
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
using the copy
storage mode. Refer to
Filesystem storage back ends for more information.
