Zero-downtime migration planning involves generating a structured MigrationPlan with phases, risks, and rollback procedures. It requires a specification detailing the source, target, type, and constraints to ensure safe transitions and rollback readiness.

The best way to migrate a legacy database without downtime is using phased rollout strategies like blue-green or Strangler Fig patterns. This approach includes compatibility analysis and validation gates to ensure safe transitions without service interruption.

Yes, zero-downtime migration planning supports automated rollback generation. The structured MigrationPlan includes rollback procedures and data reconciliation guidance to ensure systems can safely revert if validation gates detect issues during the transition.

You need compatibility analysis for infrastructure migrations when moving between architectures to identify risks in database, API, and infrastructure changes. It ensures phased rollout validation gates are met before progressing to the next migration stage.

The limitation of using Strangler Fig patterns for service migrations is the complexity of maintaining compatibility between legacy and new architectures during the phased rollout. Risk management and data reconciliation guidance are required to handle validation failures and rollback scenarios.
