Changing development teams

When a project moves to a new team, it is tempting to hand over the repository and a few passwords. That is not enough. Code is only one part of the context the next team needs to work safely.

Start with a complete handover

Without decision history, access ownership, and a clear picture of the current system, the first weeks become technical archaeology instead of product development.

The goal is not to make every document perfect. It is to make the important unknowns visible before the old contractor disappears.

Begin with the repository, including the full history of changes. History shows how the product evolved, which decisions were temporary, and where risk accumulated.

Confirm that the code belongs to the client and lives in accounts the client controls. A final zip file is not a reliable transfer of ownership.

Then create one inventory of every system the product depends on: infrastructure, domains, data, payments, analytics, email, and external APIs.

What the new team should receive

The handover should include more than a list of links:

• Repository access with commit history
• Cloud, server, database, domain, DNS, and email access
• Payment, analytics, and external API credentials
• Deployment, monitoring, backup, and recovery details

Change passwords, assign new owners, and remove accounts for people who no longer work on the project. Access transfer is part of delivery, not an administrative afterthought.

Product logic and documentation

Collect the technical specification, user scenarios, roles and permissions, API documentation, data model, architecture notes, deployment instructions, and integration details.

Design source files matter too

Ask for the editable Figma project, components, design system, icons, fonts and licenses, brand assets, prototypes, and illustration source files. Otherwise even a small interface change may have to be recreated.

Known problems should be explicit

Ask the previous team to document critical bugs, unstable modules, temporary fixes, security concerns, untested areas, and functions that fail in edge cases. It is better to inherit an uncomfortable list than to discover the same issues after launch.

Repository and ownership

Make sure the client controls the code, cloud accounts, domains, databases, and third-party services—not just individual team members.

A complete handover also includes the product rules, roles, integrations, design sources, known debt, and the release process.

Make the context transferable

The best handover includes working sessions between the old and new teams. Walk through architecture, releases, core business scenarios, difficult integrations, known risks, and the near-term roadmap.

• Repository and full development history
• Infrastructure, domains, databases, and credentials
• Product rules, roles, integrations, and data model
• Editable design files, fonts, and licenses
• Known bugs, debt, and security risks
• Release walkthrough and knowledge-transfer session

If the ideal handover is impossible

Sometimes the contractor is already gone, documentation is missing, or key decisions exist only in one developer’s memory. The project can still continue, but the first stage should restore the picture before new features are added.

The recovery sequence

Map what exists, what works, what is missing, and what must be fixed before development resumes. That inventory becomes the new team’s starting point.

A successful transition is not a file transfer. It is the recovery of ownership, access, decisions, and risks so the next team can move the product forward with confidence.

Conclusion

Before new development begins, make sure the new team can see the whole system—and that the client, not the contractor, owns the keys.
