Completing the Upgrade
Complete the following tasks to finalize the process:
Review, update, and document the domain architecture to reflect any changes that you made during the domain upgrade process.
Verify that the NETLOGON and SYSVOL shared folders exist and that the File Replication service (FRS) is functioning without error by checking the Event Viewer.
Verify that Group Policy is being applied successfully by checking the application log in Event Viewer for Event ID 1704.
Verify that all SRV, CNAME, and A resource records have been registered in DNS.
Continuously monitor your domain controllers and Active Directory. Using a monitoring solution such as Microsoft® Operations Manager to monitor the distributed Active Directory service and the services that it relies on helps maintain consistent directory data and a consistent level of service throughout the forest.
After these tasks have been completed successfully, you will have completed the in-place upgrade process.
