Direct Cutover Migration
Direct Cutover Migration is a system migration strategy where an organization switches from an old system to a new one at a single point in time, typically during a planned downtime window. It involves decommissioning the old system entirely and immediately replacing it with the new system, with no parallel operation or phased transition. This approach is often used for critical business applications, infrastructure upgrades, or when legacy systems cannot coexist with new ones.
Developers should use Direct Cutover Migration when minimizing complexity and cost is a priority, and when the new system is thoroughly tested and stable. It is suitable for scenarios with tight deadlines, limited resources, or systems that cannot run in parallel due to technical constraints, such as migrating a monolithic application to a cloud-native architecture. However, it carries high risk if issues arise post-migration, as rollback can be difficult.
