The system administrator is planning to install the BlackBerry Enterprise Server with the BlackBerry MDS Integration Service for the first time. For disaster recovery purposes, what is an important consideration?

The BlackBerry MDS Integration Service will be managed by the new BlackBerry Enterprise Server software installation. 

The BlackBerry MDS Integration Service should be installed on a separate computer. 

A knife-edge cutover of the BlackBerry Enterprise Server can point to the existing BlackBerry MDS
database.                                                                                                                                              

The existing BlackBerry MDS Integration Service must be uninstalled prior to a re-installation.                                                                                                                                              

It is possible to create a new BlackBerry MDS database if no custom applications are published to the existing
BlackBerry MDS database.
