Transform the data extract¶
Note
If your migration originates from MSR 3.x.x, proceed directly to Restore the data extract.
Once you have extracted the data from your source MSR system, you must transform the metadata into a format that is suitable for migration to an MSR 3.x.x system.
Deploy MMT as a Pod onto your MSR target cluster.
Exec into the MMT Pod.
Execute the transform command:
./mmt transform metadata msr \ --fullname <dest-MSR-instance-name> --storage-mode <inplace|copy> \ --enzipassword <source-MSR-password> \ /migration
Note
The value of
--enzipassword
is the MSR source system password. This optional parameter is required when the source and target MSR passwords differ.
On the target system, run the following command from inside a worker node on which MSR is installed:
docker run \
--rm -it \
-v /var/run/docker.sock:/var/run/docker.sock \
-v <local-migration-directory>:/migration:Z \
--mount source=msr_msr-storage,target=/storage \
--network msr_msr-ol \
registry.mirantis.com/msr/mmt:$MMT_VERSION \
transform metadata msr \
--storage-mode <inplace|copy> \
--enzipassword <source-MSR-password> \
--swarm=true \
/migration
Note
The value of --enzipassword
is the MSR source system password.
This optional parameter is required when the source and target MSR
passwords differ.
