Make sure your migration strategy includes:
An implementation sequence or a transition plan for candidate application, that shows the evolution of the new IT architecture
Information on key migration constraints, such as, data conversions and critical interfaces to legacy systems
Information on bridging routines to keep legacy systems synchronized while the new IT architecture is evolving
Information on methodologies, techniques, and tools to be used in application development environments
Initial strategy for putting new IT architecture applications into production
Staffing, skill, and training requirements to construct and test new IT architecture applications
Preliminary project plan for migration
