VB6 Maintenance and bug fixing

Stabilise and support your existing VB6 applications while you plan and execute long-term modernisation.

Modernisation takes time. In the meantime, your VB6 system must remain reliable, predictable, and safe. VB6 Maintenance focuses on disciplined, structured support that reduces incidents, removes firefighting, and creates breathing room for strategic work.

Who this is for

  • Organisations with limited or no internal VB6 expertise.
  • Teams overwhelmed by incidents, outages, or fragile behaviour.
  • Businesses needing to extend the safe life of VB6 systems during modernisation.
  • Environments where downtime or instability has significant operational impact.

Problems this service addresses

  • Frequent incidents and outages in VB6 applications.
  • Fear of making changes due to lack of understanding.
  • Missing documentation and unclear system behaviour.
  • High dependency on a single individual or external vendor.
  • Firefighting that disrupts strategic initiatives.

Benefits and outcomes

Improved stability

Fewer incidents, faster recovery, and more predictable behaviour across your VB6 estate.

Reduced operational risk

Known issues are tracked, prioritised, and addressed systematically—not reactively.

Better visibility

Clear documentation and change logs reduce reliance on individuals and support future modernisation.

Deliverables

  • Maintenance backlog with prioritised items.
  • Change logs documenting what was done and why.
  • Targeted documentation of key modules and behaviours.
  • Periodic summary reports on stability and incident trends.

Maintenance approach

1. Baseline and triage

We begin by understanding your incident profile: what breaks, how often, and with what impact. This includes reviewing logs, support tickets, and operational patterns.

2. Structured backlog

We create a prioritised backlog of defects, enhancements, and technical debt items. Each is assessed for risk, effort, and business value.

3. Controlled change

Changes are delivered in small, testable increments with clear rollback strategies. This reduces risk and improves predictability.

4. Documentation and knowledge capture

As we work, we document key behaviours, dependencies, and quirks. This reduces reliance on individuals and supports future rewrites.
