Disaster recovery involves having a platform ready to take on the technology required to continue the organizational operation. If changes or modifications are made to hardware, software or functionality, then modifications may have to be made to the disaster recovery plan. For example, if an organization makes the decision to standardize on Microsoft Vista for the desktop, the change has to be reflected within ITIL in the change management and continuity management areas. Then the DR plan has to be modified in order to have a seamless migration to the DR mode as needed.
