In the direct cutover conversion strategy, what happens to the new system?

In the direct cutover conversion strategy, the new system is implemented in one decisive action, replacing the old system entirely at a specified time. This approach means that once the new system goes live, the old system is immediately discontinued. The direct cutover method is often chosen for its simplicity and speed, as it eliminates the complexities involved in running two systems in parallel or introducing the new system in stages.

This method can lead to immediate benefits from the new system but carries risks, such as potential disruptions if the new system doesn't function as expected right away. Proper planning and testing prior to the cutover are essential to mitigate these risks and ensure a smooth transition. This contrasts with other strategies where the old and new systems may run simultaneously or be deployed incrementally, which allows for gradual adjustment and troubleshooting but often extends the timeframe for full migration and can complicate operational management.
