## Chapter 1. Introduction

This publication documents the Data Migration Facility (DMF) for SGI computer systems running the Linux operating system and the IRIX operating system release 6.5.2 or later. On IRIX systems, both 32-bit and 64-bit architectures are supported. On Linux systems, only 64-bit architectures are supported.

DMF can manage CXFS and XFS file systems on the IRIX operating system, but currently manages only XFS on the Linux operating system.

This publication includes the following information:

- Software overview (Chapter 2, “Software Overview”)

- Release package information, including its contents, hardware/software requirements, ordering information, and documentation and training support (Chapter 3, “Release Package”)

- Installation instructions (Chapter 4, “Installation Overview”, through Chapter 9, “Before You Start DMF”)

- Upgrade instructions (Chapter 10, “Upgrading DMF”)

| Note: For the most current and detailed information on changes in DMF functionality, including bugs fixed with specific releases, refer to the files accessed by the Dependencies and News buttons on the DMF installation interface (`dmmaint(8)`).
