Multi-sectorLegacy to Cloud
Before commitment, we measure. A few-week POC, a fact-based budget.
Several IT departments want to validate the feasibility of a legacy system migration before committing to a full program. Short POC on representative scope with productivity measurement and fact-based budgeting.
Delivery model
POC fixed price
Via Access International / Vivantro
Typical duration
2 to 6 weeks
Team
Architect, tech lead, 1-2 developers, partial QA
01Context
- IT department in exploration phase before committing to a legacy program
- Need to validate the technological trajectory on a representative scope
- Need to measure real productivity per migration pattern
- Need for a multi-year budget based on measurements, not assumptions
02Intervention
- Intake scoping with selection of the representative perimeter
- Application of compressed ATLAS steps (Discovery, Capture, Tests, Migration, Validation)
- Migration accelerated by vibe coding (Claude Code, Copilot)
- Parity audit on the POC scope
- Full program budgeting based on measured productivity
03Deliverables
- Functional POC on the chosen perimeter
- Characterization test suite
- Initial discrepancy registry
- Measured productivity report (lines/day, cost/pattern)
- Detailed full program budget
04Outcomes
- Technological trajectory validated or adjusted
- Productivity concretely measured (not assumed)
- Reliable budget for budgetary decision
- Option: commit to the full program or stop with usable deliverables
