Migrating Your ULTRIX System and
Network Environment
This chapter describes how to set up a DIGITAL UNIX system for
maximum compatibility with ULTRIX systems, and how to migrate file
systems from an ULTRIX system to a DIGITAL UNIX system. This chapter
also discusses the following topics:
• Using the tar and pxtar commands
• Configuring Small Computer System Interconnect (SCSI) devices
• Setting up internationalization databases
• Configuring the inetd daemon for ULTRIX compatibility
• Configuring the mountd daemon for ULTRIX compatibility

For information on migrating shadowed data from an ULTRIX
system to a DIGITAL UNIX Version 3.0 or later system, see the
Logical Storage Manager manual.
5.1 Mounting an ULTRIX File System on a DIGITAL UNIX
System
You can mount an ULTRIX File System (UFS) on a DIGITAL UNIX
system, provided the file system is created with an 8 kB block size and
there are partition tables on the disk. The DIGITAL UNIX system can read
the partition table created by the ULTRIX chpt command. Once you
mount the ULTRIX file system, you can use it as you normally would.
Using an ULTRIX file system on a DIGITAL UNIX system does not affect
its usability on an ULTRIX system.
To move an ULTRIX file system to a DIGITAL UNIX system, follow these
steps:
1. If the file system was created with a 4 kB block size, you must dump
the disk to tape or to a disk that has a file system created with an 8
kB block size.
