titan migrate¶

Migrate data from a running container into new Titan repository. Given a stopped container with volumes mounted from the host system, this command will create a new container with an identical configuration, and then copy over the data into the new repository. For more information, see the Migrating Existing Containers section.

Note

The migrate command will only work if the volumes have been mounted from host system. Migrating local to the container, or from a different volume driver, is not supported.
