Verify the source system configuration¶
The first step in migrating your MSR 2.9.x system to an MSR 3.0.x system is to verify the configuration of the source system.
docker run \
--rm \
-it \
registry.mirantis.com/msr/mmt:<mmt-version> \
verify msr \
--source-mke-url <mke-url> \
--source-username <mke-admin-username> \
--source-password <mke-admin-password> \
--source-url <msr-2.9-url> \
--storage-mode <inplace|copy> \
--source-insecure-tls \
/migration
Note
Migrations that use the copy
storage mode and a filesystem
storage
back end must also include the --mount
option, to specify the MSR 2.9.x
Docker volume that will be mounted to the MMT container at the /storage
directory. As --mount
is a Docker option, it must be included prior to
the registry.mirantis.com/msr/mmt:<mmt-version>
portion of the command.
--mount source=dtr-registry-<replica-id>,target=/storage
To obtain the MSR replica ID, run the following command from within an MSR node:
docker ps --format '{{.Names}}' -f name=dtr-rethink | cut -f 3 -d '-'
