Migrating complex systems often requires careful planning and execution to avoid disruptions. A recommended strategy involves gradually phasing in new features in the target system (system2) while simultaneously decommissioning the legacy system (system1). Communicating the benefits of the new system to customers can enhance their experience and acceptance of the changes. Emphasizing quicker feature delivery can persuade customers about the advantages of using system2 over system1. Avoiding complex migrations in system1 is highlighted, indicating a preference for cleaner transitions.
