Internal Systems Handover

Your team is moving on. Your systems don't have to suffer.

When in-house developers leave, retire, or get reassigned, the systems they built don't stop needing support. We provide a smooth, structured handover and ongoing managed support so your business-critical systems keep running.

When internal systems need external support

These are the situations we see most often. If any of them sound familiar, we can help.

Key developer leaving

Your lead developer has resigned, retired, or moved roles. They built the system and all the knowledge is in their head. You need someone to step in before they leave.

Team capacity stretched

Your in-house team is focused on new priorities and can't maintain legacy systems alongside new work. Something has to give — and it shouldn't be the systems your business runs on.

Skills gap

The system was built in a technology your current team doesn't know well. Finding and hiring specialists takes time you don't have.

Cost and risk reduction

Maintaining internal systems in-house is expensive and creates single points of failure. Outsourcing to a managed support partner can reduce costs while improving resilience.

Everything your in-house team used to handle

We don't just keep the lights on. We provide the full range of support your systems need to stay healthy and evolve with your business.

Bug fixes and incident response

When something breaks, we fix it. SLA-backed response times, proper root cause analysis, and permanent fixes rather than workarounds.

Feature development

Your business keeps evolving and your systems need to keep up. We deliver new features and enhancements through the same managed support arrangement.

Security patching and updates

Framework updates, dependency patches, and security fixes applied on a regular schedule. No more running years-old versions with known vulnerabilities.

Infrastructure management

Hosting, monitoring, backups, and disaster recovery. We take on responsibility for keeping your systems available, performant, and secure.

Performance optimisation

Slow queries, memory leaks, and scaling bottlenecks identified and resolved. We monitor performance continuously and address issues proactively.

Documentation and knowledge capture

We document the system as we learn it — architecture decisions, runbooks, deployment procedures, and operational knowledge that should never live in one person's head.

A structured handover that protects your business

We've refined this process across multiple handover engagements. It's designed to minimise disruption and capture knowledge before it walks out the door.

1-4 weeks

Knowledge transfer

We work alongside your existing team (or outgoing developers) to understand the system. This includes:

  • Architecture walkthrough and documentation
  • Access to repositories, infrastructure, and tooling
  • Review of known issues, workarounds, and technical debt
  • Understanding business context and user workflows

If the outgoing team has limited availability, we adapt — we're experienced at reverse-engineering systems from code alone.

2-4 weeks

Parallel running

We run support alongside your existing team for a transition period. This lets us build confidence, prove our understanding, and catch anything that wasn't covered in knowledge transfer.

During this phase we also:

  • Set up monitoring and alerting
  • Create runbooks for common operational tasks
  • Establish CI/CD improvements where needed
  • Agree SLAs and reporting cadence

Full handover

We take full responsibility for the system. You get:

SLA-backed support with agreed response and resolution targets.

Monthly reports covering support activity, system health, performance metrics, and recommendations.

Quarterly reviews where we assess system health, calibrate support levels, and plan upcoming work.

A named team who knows your system inside out and is available when you need them.

Your dedicated support team

A permanent, UK-based team who take ownership of your systems and become the experts your business needs.

L

Lead Engineer

Takes ownership of the system during knowledge transfer and remains the primary technical authority. Knows the codebase deeply and leads all significant changes.

B

Backend Engineer

Handles day-to-day development, bug fixes, and feature work. Ensures the system remains stable, secure, and performant.

D

DevOps Engineer

Manages infrastructure, CI/CD pipelines, monitoring, and deployments. Ensures the system can be deployed safely and recovered quickly.

D

Delivery Manager

Your main point of contact. Manages priorities, coordinates the team, produces reports, and runs quarterly reviews.

"The team are experienced, practical, people who quickly cut to the important issues."

Frequently asked questions

What if the original developer has already left?

We handle this regularly. While knowledge transfer with the original team is ideal, we're experienced at reverse-engineering systems from code, infrastructure, and user behaviour. It takes longer, but we get there.

Can you work with older technology stacks?

Yes. We work with a wide range of technologies including .NET Framework, classic ASP, PHP, Node.js, Python, and more. During scoping we'll confirm our team has the right expertise for your stack.

How long does the full transition take?

Typically 4-8 weeks from kick-off to full handover, depending on the complexity of the system and availability of the outgoing team. We can compress this timeline if urgency demands it.

Can you also modernise the system over time?

Yes. Many of our handover engagements evolve into gradual modernisation programmes. Once we understand the system, we can plan and deliver incremental improvements, framework upgrades, cloud migration, architecture improvements, as part of the ongoing support arrangement.

What happens if we want to bring support back in-house later?

That's fine. We document everything we do and maintain clear handover documentation throughout the engagement. If you decide to bring support back in-house, we'll run a reverse knowledge transfer to ensure a smooth transition.

How is this different from your general managed support?

Our general managed support is designed for systems we've built or that are already well-documented. Internal systems handover includes a structured knowledge transfer and transition phase specifically designed for inheriting systems from other teams.

Don't wait until your last developer has left

The best time to plan a handover is before it becomes urgent. Book a free consultation and we'll assess your situation, scope the transition, and give you a clear plan.
