Answer 8 questions
Multi-axis scoring: architecture state, codebase, data model, business criticality, SaaS replacement viability, regulatory frame, timeline pressure, and engineering team appetite. Each option weights the three modernization paths.
- 02
See the path scores
Three-axis breakdown: replatform / rearchitect / replace. The headline recommendation is the highest-scoring path; the breakdown shows how close the alternatives are.
- 03
Read the next steps
Each modernization path has a different sequence. Replatform: workload disposition + IaC + wave plan. Rearchitect: bounded-context decomposition + strangler-fig. Replace: SaaS gap analysis + data migration + sunset plan.

Bring it to a platform architect
The output is directional. Bring it to a 30-minute discovery call and we'll calibrate against your actual data model, integration surface, and regulatory frame.
Common questions
Before you start.
- 01
How is the scoring calibrated?
Each option carries weights across the three axes (replatform / rearchitect / replace) tuned against patterns we've observed across modernization engagements. The weights aren't optimistic; they reflect the actual frequency of each path being the right call across the conditions described.
- 02
What if the result is close across paths?
Close scores typically mean the right answer is hybrid. Common patterns: replatform some workloads while rearchitecting one critical bounded context; replace a non-differentiating workload while rearchitecting the rest. We design hybrid paths in real engagements; the calculator gives you the directional starting point.
- 03
Why is 'replatform' usually the conservative pick?
It is: by design. Replatform is the lowest-risk path that produces real modernization benefit. We over-weight conservatism in the calculator because most failed modernizations failed by attempting too much rearchitecture in one program. Replatform is rarely the wrong answer; rearchitect can be.
- 04
When should we just rebuild from scratch?
Rarely. Greenfield rebuilds carry the highest risk and the longest timeline. Replace (with a SaaS or commercial alternative) is the right answer when a viable product exists; otherwise, rearchitect is usually a better path than greenfield-rebuild even when it feels heavier.
- 05
Can we run this for multiple systems?
Yes: retake it for each system. In an enterprise modernization program we typically score every workload in the inventory and produce a per-workload disposition. The calculator supports the per-workload analysis as a starting point.
- 06
Does the result account for cost?
Indirectly. Timeline pressure, regulatory frame, and engineering capacity questions push the scoring toward the lower-cost paths when constraints favor them. For an explicit cost projection, follow up with a discovery engagement where we model implementation, ongoing, and total-cost-of-ownership for each path.
