In this chapter, we covered the new features in Windows Server 2003
and some of the differences with Windows 2000, most of which were
instigated by real-world deployment issues. We then went over how you
can enable new features with the use of functional levels and why
they are necessary. Next we discussed the ADPrep process and how that
must be done before the first Windows Server 2003 domain controller
can be promoted. Once you have your forest and domains prepared, you
can start the upgrade process. We described some of the important
issues to be aware of when upgrading, and finally what to do after
you've completed the upgrade.
While this chapter focused mainly on upgrading from an existing
Windows 2000 Active Directory infrastructure, in the next chapter we
discuss some of the key issues with migrating from Windows NT
straight to Windows Server 2003 Active Directory.
