Notes:

• The class MUST NOT exist on the destination grid.
• If neither the --export or --import options are specified, the class is migrated FROM the remote grid.
• SSH agent and agent forwarding must be enabled on the client machine for the remote grid access to work.
• The --nocompress option is useful when migrating classes that have very large volumes.
