Zusammenfassung:	Systems and methods for migrating a metadata server are provided. A source metadata server is transferred to a new metadata server. During the migration process, only one of the metadata servers is active. Over time, data is transferred to the new metadata server until the new metadata server is fully synchronized with the source metadata server. Then metadata service process is terminated on the source metadata server and started on the new metadata server. The new metadata server transitions to read/write and normal file system operations are resumed at the new metadata server.
