76 Chapter 5 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 10.1 or 10.2 server’s hard disk needs reformatting, or does not meet the
minimum version 10.3 hardware requirements (see “Understanding System
Requirements for Installing Mac OS X Server” on page 79).
• You want to move data and settings you’ve been using on a version 10.1 or 10.2
server to a different server.
• The server version you’ve been using is earlier than version 10.1.
Read the migration guide to understand what data and service settings can be
preserved and reused on version 10.3. The migration guide provides instructions for
both reusing existing server hardware—called migrating in place—and migrating from
one computer to another.
Define an Integration Strategy
Integrating Mac OS X Server into a heterogeneous environment has two aspects:
• Configuring Mac OS X Server to take advantage of existing services
• Configuring non-Apple computers to use Mac OS X Server
The first aspect involves primarily directory services integration. Identify which
Mac OS X Server computers will use existing directories—such as Active Directory,
LDAPv3, and NIS directories—and existing authentication setups—such as Kerberos.
See the Open Directory administration guide for options and instructions. Integration
may be as easy as enabling a Directory Access option, or it may involve adjusting
existing services and Mac OS X Server settings.
The second aspect is largely a matter of determining the support you want to offer
Windows computer users of Mac OS X Server. The Windows services administration
guide tells you what’s available.
Define Physical Infrastructure Requirements
Determine whether you need to make any site or network topology adjustments
before installing and setting up servers.
• Who will administer the server, and what kind of server access will administrators
need? Classroom servers may need to be conveniently accessible for instructors,
while servers that host network-wide directory information should be secured with
restricted access in a district office building or centralized computer facility.
Because Mac OS X Server administration tools offer complete remote server
administration support, there are very few times a server administrator should need
physical access to a server.
