Before you back up the previous DRA version registry or begin the upgrade process, ensure you synchronize the server sets so each Administration server contains the latest configuration and security settings.
NOTE:Ensure you made all necessary changes to the delegation, configuration, or policy settings for this MMS. Use the primary Administration server to modify these settings. Once you upgrade the primary Administration server, you cannot synchronize delegation, configuration, or policy settings to any Administration servers running previous DRA versions.
To synchronize your existing server set:
Log on to the primary Administration server as the Built-in Admin.
Start the MMC interface.
In the left pane, expand Configuration Management.
Click Administration servers.
In the right pane, select the appropriate primary Administration server for this server set.
Click Properties.
On the Synchronization schedule tab, click Refresh Now.
Verify the successful completion of the synchronization, and that all secondary Administration servers are available.
