Before committing to a modernisation or migration project, you need to understand what you're actually dealing with. The Legacy Software Assessment is a fixed-scope engagement that gives you a clear picture of your system, your options, and the risks involved — without requiring you to hand over a large budget.
What is a Legacy Software Assessment?
A structured analysis of your legacy application — working from the running software, binary files, and data — that produces a documented understanding of what the system does, how it works, and what it would take to recover, document, or replace it.
The assessment is deliberately limited in scope so you can make a decision with real information rather than assumptions.
What you receive
Architecture Overview
How the system is structured — components, modules, dependencies, and how data flows through the application.
Database Analysis
Schema documentation, table relationships, data types, and an assessment of data quality and extractability.
Technology Stack Identification
What the application was built with, what runtime dependencies it has, and what platform risks exist.
Business Rule Extraction
Key calculations, validation rules, and business logic embedded in the application — documented in plain language.
Modernisation Options
A realistic set of options for what to do next — from data extraction only, through to full rebuild — with pros, cons, and indicative effort.
Risk Assessment
Where the system is fragile, what could break it, what would be lost if it stopped working today, and how to reduce exposure.
Who is this for?
The assessment is designed for:
- IT managers who need to brief leadership on a legacy software risk
- Business owners who have inherited software they don’t understand
- Finance and operations teams whose data is trapped in old file formats
- Technology leads planning a modernisation project who need a starting point
What I need from you
- Access to the running application (if still functional)
- Any available data files or database files
- Any documentation that exists (even partial)
- A conversation with anyone who has operational knowledge of the system
I work with what’s available. Lack of source code and lack of documentation is the normal starting point.
Request your assessment
Fill in the form below and I'll contact you to discuss scope, timeline, and cost. There's no obligation — the assessment itself gives you enough information to decide what to do next.
