Conclusion

Cutover is a complex activity that involves more than re-routing traffic to new systems. This complexity depends on many factors, including business criticality, number of upstream and downstream systems, number of users, and more. It’s important that your team understand all the intricacies around people, process, and technology for your cutover phase. Based on these complexities, you could identify, develop, and adopt the communication and governance plans for the pre-cutover, cutover, and post-cutover activities of your migration. Finally, we recommend that you use the existing knowledge of your on-premises system to estimate the duration of your cutover. It can be a useful exercise to work backward from the desired outcome of the cutover.
