44 Chapter 2 Before You Begin
When you can’t use the upgrade approach, you can migrate data and settings. You’ll
need to migrate, not upgrade, when:
 A version 10.2.8 or 10.3 server’s hard disk needs reformatting or doesn’t meet the
minimum version 10.4 system requirements. “Understanding System Requirements
for Installing Mac OS X Server” on page 54 describes the minimum requirements.
 You want to move data and settings you’ve been using on a version 10.2.8 or 10.3
server to different server hardware.
 The server version you’ve been using is earlier than version 10.2.8.
Migration from versions 10.3.9, 10.2.8, 10.1.4, 10.1.5, and 1.2; and from AppleShare IP
version 6.3.3 are supported. When you migrate, you install and set up a version 10.4
server, restore files onto it from the earlier server, and make some manual adjustments
as required.
Read the upgrading and migrating guide for complete information.
Note: You can’t update to a later 10.4 version by using a Mac OS X Server installation
disc. For example, you can’t use an installation DVD for version 10.4.7 to update an
earlier version. To learn how to update to the latest version, see “Keeping Current” on
page 38.
Migrating From Windows NT
Mac OS X Server can provide a variety of services to users of Microsoft Windows 95, 98,
ME, XP, NT 4, and 2000 computers. By providing these services, Mac OS X Server can
replace Windows NT servers in small workgroups.
The Windows NT migration guide provides instructions for migrating users, groups,
files, and more from a Windows NT server to Mac OS X Server.
