Backing up the Administration server registry ensures that you can return to your previous configurations. For example, if you must completely uninstall the current DRA version and use the previous DRA version, having a backup of your previous registry settings allows you to easily recover your previous configuration and security settings.
However, be careful when editing your registry. If there is an error in your registry, the Administration server may not function as expected. If an error occurs during the upgrade process, you can use the backup of your registry settings to restore the registry. For more information, see the Registry Editor Help.
IMPORTANT:The DRA server version, Windows OS name and managed domain configuration must be exactly the same when restoring the registry.
IMPORTANT:Before upgrading, back up the Windows OS of the machine that is hosting DRA or create a virtual machine snapshot image of the machine.
To back up the Administration server registry:
Run regedit.exe.
Select the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mission Critical Software\OnePoint key.
On the Registry menu, click Export Registry File.
Specify the name and location of the file to save the registry key.
Click Selected branch.
Click Save.
