Legacy System Rescue & Stabilisation

Your system keeps breaking, runs slowly, or was handed over without enough documentation. We investigate the immediate operational risk, restore control, document what we find, and leave you with a stable baseline and a clear decision about what happens next. This is a project-based rescue service, not an ongoing support plan.

Why Systems Break (And How We Fix Them)

Most broken systems are not failures of the original idea. Requirements changed, dependencies aged, the original developer moved on, or the system was never properly documented. We start by restoring visibility and reducing the risks that are actively affecting operations. Feature work waits until the system is understood and stable.

A Rescue Engagement Produces

A prioritised incident and risk list, repaired critical failures, a map of code and infrastructure dependencies, recovery observations, and a practical recommendation: hand the stable system back, modernise selected components, or move into a separately agreed managed-support service.

What We Diagnose & Stabilise

Focused technical intervention when an inherited or aging system is disrupting normal operations

Legacy .NET Fault Diagnosis

Find the failure path and restore a dependable baseline

  • VB.NET application support
  • Classic ASP and ASP.NET 2.0-4.x maintenance
  • Older SQL Server versions (2008-2016)
  • Bug fixes and security patches
  • Angular application support and bug fixes

Performance & Stability Fixes

Your system works but it's slow or unreliable. We investigate the actual cause, not just the symptoms, and fix it properly.

  • Performance tuning and bottleneck resolution
  • Database query optimisation
  • Memory leak identification and fixes
  • Stability improvements and crash prevention

Technical Debt Reduction

Strategic refactoring for improved maintainability

  • Code quality assessment and improvement
  • Gradual refactoring of problematic modules
  • Improved error handling and logging
  • Documentation and knowledge preservation

WordPress & PHP Fixes

WordPress sites break in specific ways. Broken plugins, failed API integrations, database errors. We diagnose and fix them properly, not just patch them.

  • Broken plugin troubleshooting and fixes
  • WordPress API integration repair
  • PHP version upgrade compatibility
  • Database errors and performance issues

Database Migration & Upgrades

SQL Server version upgrades and schema modernisation

  • SQL Server 2008-2016 to 2019/2022 migration
  • Schema optimisation and normalization
  • Data integrity validation and cleanup
  • Performance tuning post-migration

Documentation & Knowledge Transfer

Undocumented systems are a liability. If only one person knows how it works, that's a risk. We document your system so any developer can maintain it.

  • Business logic documentation
  • System architecture mapping
  • Hybrid approaches (legacy + modern components)
  • Team knowledge transfer and training

How We Approach a New System

Proven methodologies for managing change in mission-critical systems

1

System Health Assessment

We look at everything. Code, database, integrations, documentation. Then we tell you honestly what we found, including the things you might not want to hear.

2

Stabilisation & Risk Mitigation

We fix the things that are actively breaking operations first. Security vulnerabilities, crashing bugs, data integrity issues. Everything else comes after the fire is out.

3

Strategic Modernisation Planning

Once the system is stable, we work out a realistic roadmap. Not everything needs rebuilding. Some things just need tidying. We prioritise based on what saves you the most money or risk first.

4

Incremental Improvement

Module by module. We run old and new components side by side during any transition. You never have a day where the system just stops working.

5

Handover & Next-Step Decision

We document the stable baseline and hand it back. If you need phased modernisation or ongoing managed support, that becomes a separate, clearly scoped engagement rather than an open-ended rescue project.

Frequently Asked Questions

Common questions about diagnosing and stabilising inherited systems

Should we maintain our current system or rewrite it?

Rewrites are expensive and often fail. If your system has good business logic underneath the mess, phased improvement is almost always better. We'll assess what you have and give you a straight answer on which path makes sense. We don't push rewrites unless they're genuinely necessary.

Can you support a system built by another developer?

Yes. We take over systems built by anyone, in most technologies. We do a review first, tell you what state it's in, and agree on a clear scope before we commit to anything.

What is phased modernisation?

Phased modernisation means improving your system in stages rather than replacing it all at once. We extract one module, rebuild it with modern technology, connect it via API, and run old and new side by side. This spreads cost over time and means the business keeps running throughout.

How do you handle undocumented systems?

We work through it systematically. As we go, we document the architecture, business logic, dependencies, and integration points. That includes code comments, diagrams, process flows, and runbooks. We also transfer knowledge to your internal team through pairing sessions and training, so it's not just us who understands the system by the end.
