Taking Over a Software Project from Another Vendor

Web Application Maintenance After a Developer Handover

The developer stopped answering. The agency closed, or the contract ended badly. Now the system your business depends on has no one looking after it, and you are not sure who holds the passwords, where the code is, or what would happen if the server went down tonight.

Taking over a software project from another vendor can be difficult when documentation, credentials and deployment knowledge are missing. But with a structured takeover process, the system can usually be secured, assessed and stabilised before you decide what to do next.

The first priority is not to rebuild the system. It is to regain control, understand what you have, stabilise it and then decide whether to maintain, refactor or replace it.

01 · AccessFirst week of a Software Project Takeover

The first step in any application takeover is gaining control of the accounts and infrastructure the system depends on. List every account and confirm that your company, not a former supplier or employee, is the owner.

This access review is also an important part of application security assessment, because former employees, vendors and unused accounts can remain a security risk after a handover.

Change passwords and rotate API keys once you have access, so former suppliers can no longer reach the system. If the previous vendor will not hand over access, check what your contract says about code ownership and handover, and take legal advice before the situation becomes urgent.

02 · AssessmentAssess the Software and Infrastructure

A technical assessment should establish how the software works, what it depends on, and whether another development team can safely maintain it.

• Does the code in the repository match what is running in production?
• Which framework, language and server versions are in use, and are they still supported?
• Can the system be deployed by someone new, from written steps?
• Are there automated tests, and do they pass?
• What are the most serious security issues?
• Where is the business logic that matters most, such as pricing, invoicing and permissions?
• Are there third-party services, APIs or integrations that nobody currently maintains?
• Are production credentials, certificates, domains and deployment environments documented?

The result should be a practical code and infrastructure assessment, not simply a list of technical problems. It should identify the highest risks, dependencies, maintenance requirements and recommended next steps.

03 · StabiliseStabilise Before Changing Anything

Once the application has been assessed, the next stage of web application maintenance is stabilisation. The goal is to reduce immediate operational and security risks before making major changes.

1. Back up everythingCode, database and uploaded files, stored where you control them, and test a restore.
2. Add monitoringUptime and error alerts, so you hear about failures before customers do.
3. Fix critical security and maintenance issuesExposed credentials, unsupported software with known vulnerabilities, missing access controls.
4. Write down how to deployAnd do one small, low-risk deployment to prove the process works.
5. Freeze large changesUntil the team understands the system; small fixes only.

04 · DecisionDecide the Path

Once the system is secure and understood, you can choose the right application maintenance or modernization path.

Replacing is tempting after a bad experience, but it is often the most disruptive option, and the old system has to keep running meanwhile. Make the decision on the assessment, not on frustration. Our application modernization service covers the modernisation route, and technical documentation makes sure the next handover is easier.
