What's inside
- A table of four seam types (data, process, integration and UI), each with a definition, a key question and examples.
- A seam dependency map: each seam's type, what it depends on, what depends on it, shared state, cut-over risk and sequence.
- Seven cut-over steps, from identifying seams to retiring the old component.
- A rollback plan with five questions to answer before each cut-over.
- Five common failure modes, such as seams that are too large and shared databases left unaddressed.
- The PowerPoint version has five slides: title, seam inventory, dependency map, cut-over sequence and rollback plan.
Format: PDF (3 pages) and PowerPoint file.
How to use it
Use it to plan an incremental modernization, filling in the sequence column last, once all dependencies are mapped.
