Practical website guidance
Useful advice without the waffle
This article is written for small-business owners who want a clearer website, better enquiry flow and sensible next steps without unnecessary jargon.
Legacy systems
Old business software usually costs more to keep alive than to replace properly
Businesses often contact Crawford Software Works with an application that still runs on Windows 10, Windows 7 or even Windows XP. It might still work, but there are usually hidden costs: security risk, instability, compatibility problems and growing difficulty finding toolchains that can build for legacy operating systems.
Our recommendation: rebuild for Windows 11 or Linux, then migrate your data
For security and cost reasons, Crawford Software Works usually recommends building a modern replacement for Windows 11 or Linux and then exporting or migrating the data from the old system into the new one.
In practice, this is often cheaper, safer and more useful than trying to keep an old platform alive.
Why legacy operating system builds cost more
Toolchain limits
Older targets may require old compilers, runtime components or dependencies that are no longer supported.
Testing risk
It may not be possible to test safely in-house, which can mean disruptive live testing on the client machine.
Higher support cost
Extra investigation, compatibility work and edge-case testing can quickly cost more than a clean rebuild.
Security concern
Old operating systems and dependencies can leave important business data exposed to unnecessary risk.
Data migration is usually the cheapest part
If your application stores data in a database, spreadsheets, exported files, customer records or structured documents, the data can often be exported and moved into a modern system. This approach keeps the useful business history without keeping the old operating system constraint.
Linux can reduce licensing costs
In many cases, Linux can be a cost-effective platform for custom business systems. Depending on your setup, it may avoid a new Windows licence while giving the business a stable and secure environment for databases, dashboards, automation tools and internal workflows.
Legacy feasibility check: £150
If you specifically need a build for an older operating system, Crawford Software Works can assess feasibility first. The legacy feasibility check costs £150 and looks at whether an older build or patch route is realistically possible.

What a modern rebuild can improve
Modernising an older system is not only about replacing technology. It is also a chance to improve the user journey, data flow, security and long-term maintainability. A rebuild can keep what works, remove friction and make everyday tasks clearer for the people who actually use the system.
Next step
If you are unsure which route is best, send a short description of what the system does, what operating system it currently runs on and what data needs to be kept. Crawford Software Works can recommend a practical next step.
