Node.js Migration in Durham
Node.js version migrations for Durham organisations, where the schedule is published and the consequence of ignoring it is not. Releases have defined support windows, and once a version passes end of life it receives no further security patches — so an application on an old runtime is accumulating known vulnerabilities with no route to fixing them.
Why this comes up
The problem
Production runs a version that stopped receiving security updates over a year ago, and nobody scheduled the upgrade.
What you get
What we deliver
- Current support position established for the runtime and the major dependencies
- Native modules identified, since these need rebuilding and sometimes replacing
- Deprecated APIs found and updated before the version change rather than after
- Module system position resolved where a codebase mixes both styles
- Upgrade tested against real load, not only against the test suite
- A cadence agreed so the next version change is routine

Working in Durham
North East
Durham's economy is dominated by its university and cathedral, so the commercial base is small and much of the local demand comes from spinouts and suppliers attached to the institutions rather than from independent industry.
Research spinout software and visitor systems, usually on institutional procurement timelines rather than commercial ones.

Node.js Migration in Durham — common questions
- How urgent is an unsupported runtime?
- It depends on exposure, and the direction is one-way. No patches means every vulnerability discovered after that date remains open permanently, so an internet-facing service on an unsupported version is a position that only worsens with time.
- What usually breaks?
- Native modules and abandoned packages. Anything compiled against the old runtime needs rebuilding, and dependencies that stopped being maintained may never support the new version — which turns part of the upgrade into a replacement exercise.
- Should we jump to the newest version?
- Move to a supported long-term release rather than the newest available. That gives the longest window before the next required move, and avoids the churn of tracking versions that will themselves reach end of life within months.
- Is the test suite enough to verify it?
- Not on its own. Runtime upgrades change performance characteristics and memory behaviour in ways tests do not exercise, so a period running the new version under realistic load before full cutover is what catches the remaining surprises.
- Do you work with businesses across County Durham?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout North East, including Durham and the surrounding County Durham area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Durham businesses do you usually work with?
- Research spinout software and visitor systems, usually on institutional procurement timelines rather than commercial ones. Beyond that we work across Higher Education, Tourism & Heritage, Public Sector, Retail and Research.
- Do you cover the areas around Durham?
- Yes — we work throughout North East, including Newcastle, Sunderland, York. Durham is an urban area of roughly 70,000+, and we take on work across the wider County Durham region rather than the city boundary alone.
