Prerequisites for uninstalling SnapManager

If you have used SnapManager to manage your Exchange databases, and you plan to reinstall SnapManager later, ensure that you record the drive letter and the path of the SnapInfo directory locations before proceeding.

If you have set up a single SnapInfo directory for all databases on your host, then record the drive letter and the path of the LUN that contains a single SnapInfo directory for all Exchange servers, and their associated databases.

If you have set up multiple SnapInfo directories, then record the drive letter and path of each LUN that contains a SnapInfo directory.

SnapManager reports record the current SnapInfo directory locations in the most recent logs contained in the Backup folder and in the Config folder.

After you reinstall SnapManager, ensure that you reconfigure SnapManager with the same SnapInfo directory locations that SnapManager had used earlier.

• Comparison of interactive versus unattended uninstallation
  You can run the software uninstallation utility for SnapManager in either the interactive mode or the unattended mode. SnapManager guides you through the interactive mode; the unattended mode requires that you type certain commands and then uninstallation takes place on its own.
• Moving Exchange data to a local disk
  Before you uninstall SnapManager, you might want to move your Exchange data store from the storage system to a local disk, so that there is no data loss if you face a problem in the uninstallation operation.
