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
