Application consolidation and retirement of heritage systems present significant opportunities and threats to any organization. Leveraging of latest capabilities and productivity enhancing features of the new system as well as cost savings due to consolidation of heritage systems present significant business benefits. However, most system migration or consolidation projects tend to be significant organizational change initiatives and if not managed carefully, can lead to business black outs, cost overruns, and slow adoption of the new system. With eQube®-MI, \'bulk load + delta\' approach or \'bi-directional sync\' approach can be used for orderly retirement of legacy systems without business disruptions or blackouts. Also, migrated data can be simultaneously populated in a training instance of the new system for faster user adoption. These approaches dramatically reduce the risks in consolidation of applications while providing a responsible path forward.
