Should You Rebuild, Wrap, or Replace?
Eighteen questions across six dimensions help you choose a modernization approach that minimizes risk and disruption — and tells you which path the system itself is pointing toward.
- A scored profile across 6 dimensions — see exactly where you're strong and where the gaps are.
- Your biggest opportunities, mapped to specific next moves.
- A personalized video walkthrough from Shawn (optional) — a real read on your results.
Most legacy modernization decisions go wrong not in the execution but in the choice — teams pick rebuild, wrap, or replace before they've honestly read the system. A clear-eyed legacy system modernization assessment looks past the frustration with old technology at the factors that actually decide the right path: whether the embedded business logic is a true differentiator or a commodity, how stable the system is, how many dependencies a change has to satisfy, how well it's documented, and how clean the data is.
This free legacy modernization assessment scores your system across six dimensions and returns a clear recommendation — lean toward rebuild, wrap, or replace — in about six minutes. It's built from 27 years of leading large, multi-year modernization programs across Fortune 500 and growth-stage companies, the same lens an enterprise modernization advisor would bring to your first conversation.
What the legacy modernization assessment measures
The right modernization approach isn't a matter of taste — it's a function of the system itself. The assessment scores six dimensions independently so you can see exactly what's driving the decision: Business-Logic Value (is the embedded logic a differentiator worth preserving or a commodity you could buy), System Stability (is it steady enough to modernize in place), Integration Complexity (how many dependencies a change must account for), Documentation & Knowledge (does anyone still understand how it works), Data Quality (can the data move cleanly to something new), and Business Urgency (how much time the business will actually give you). The final question maps the specific forces — cost, performance, compliance, talent risk, a pending transaction — that any plan has to satisfy.
How to choose between rebuild, wrap, and replace
The decision hinges on three things working together. First, whether the business logic is a genuine differentiator: if it is, you preserve it (rebuild or wrap); if it's a commodity, replacing with a proven product usually wins. Second, stability: a fragile, poorly understood system is dangerous to rebuild all at once, which is why wrapping it behind clean APIs is often the lowest-risk first move. Third, dependency sequencing: the order in which capabilities and data move is what separates a smooth modernization from a stalled one. Wrapping frequently becomes the staging ground for a later rebuild or replace, because it contains the risk while you tame the dependencies.
What you get at the end
You'll see an overall modernization readiness score, a band that tells you which approach your system leans toward — from Replace-Leaning through Modernize From Strength — a per-dimension breakdown of where your strengths and risks are, and a map of the drivers behind the decision. From there you can request a personalized video walkthrough: a short, recorded read on your specific results, which path the profile suggests, and how to sequence the work to keep risk and disruption low. No generic sales deck.
Frequently asked questions
What is a legacy system modernization assessment?
A legacy system modernization assessment is a structured evaluation of an aging system across the factors that determine the right path forward — the value of its embedded business logic, its stability, its integration complexity, how well it's documented, and the quality of its data. Rather than assuming a single approach, it weighs these together to indicate whether you should lean toward rebuilding, wrapping, or replacing the system.
Should I rebuild, wrap, or replace my legacy system?
It depends on three things. Rebuild when the embedded logic is a genuine differentiator and the system is stable and understood enough to take apart deliberately. Wrap — put clean APIs around what exists — when the system is valuable but too risky to change wholesale right now; it contains the risk and often becomes the staging ground for a later move. Replace when the core function is a commodity a proven product can cover. This assessment scores your system to show which way it leans.
How long does the assessment take?
About six minutes. It's 18 scored questions across six dimensions plus a final driver-mapping question. Your progress auto-saves, so you can leave and resume without losing answers.
Is the assessment free?
Yes. The assessment and your scored results are completely free. You can optionally request a personalized video walkthrough of your results, which is also free.
Who is this assessment for?
It's built for executives, founders, and technology leaders weighing what to do with an aging system — and for teams preparing for a merger, acquisition, or sale where the state of a legacy platform matters to the outcome.
