Part 3: Windows (Web design software) Server 2003 Upgrades and Migrations
Part 3: Windows Server 2003 Upgrades and Migrations Upgrading to Windows Server 2003 The Active Directory Preparation tool completes the following tasks: . Implements schema updates, integrating the Windows Server 2003 schema with existing schema. . Improves security on directory objects, enhances security descriptor defaults, and ends reliance on the Everyone group for access to services. . Creates new containers and directory objects. (You can view these objects to verify that the schema was updated correctly.) Before you upgrade an Active Directory forest, verify that you have end-to-end replication of the domain information to all domain controllers in each domain and throughout the forest. At least one inbound and outbound replication partner for each directory partition must exist the schema and configuration partitions are replicated throughout the forest, while the domain directory partition is replicated to all domain controllers in the domain. For the purposes of disaster recovery, it is critical that backups of the Schema Master and a domain controller in each domain be made prior to beginning the upgrade process. Prior to starting the upgrade, verify that the system volume (Sysvol) information (specifically the default domain policy and the Default Domain Controller Policy) is correctly replicated to all domain controllers in the domain. . A tool called the FRS Health Check (Health_chk.cmd) part of the Support Tools installed from the SupportTools folder on the Windows Server 2003 distribution CD can be used to determine the status of the system volume replication (and many other factors). . Alternatively, you can use Gpotool.exe (in the Windows Server 2003 Resource Kit) with the /Verbose parameter to assess whether policies are being consistently applied within the domain. Chapter 8 Troubleshooting Issues with upgrading domains hosting Microsoft Exchange 2000 Server There are problems with upgrading domains that have integrated Exchange 2000 Server essentially, Exchange 2000 Server defines three attributes differently than Windows Server 2003 does, and upgrading domains that have been modified by Exchange 2000 Server can result in mangled attributes. For details on this problem and how to work around it, see Microsoft Knowledge Base article 314649. Caution To avoid domain corruption, before you upgrade an Active Directory forest, all domain controllers within the forest require installation of either Service Pack 1 with QFE 265089 or Service Pack 2 see Microsoft Knowledge Base article 331161.
