Software Project Handover Checklist: Moving to a New Development Team

When a software project changes teams, repository access is only the beginning. The incoming team needs enough information and appropriate access to build the product, understand its dependencies, verify behaviour and manage changes within its agreed responsibilities.

This checklist provides a starting point for a handover between development providers or between an external and internal team. Adapt it to your product and the scope of the transition. It is a general planning resource, not a client case study.

1. Agree the scope of the handover

Start by defining what is moving and what will remain with its current owner. A mobile app, backend and cloud environment may have different maintainers. Avoid assuming that taking over one component means taking responsibility for all of them.

Record the components included, the outgoing and incoming contacts, the product owner who can approve decisions and the intended transition date. Define any support expected from the outgoing team and how unresolved questions will be handled.

Before closing this step, check that each party can describe its responsibilities during and after the transition.

2. Identify the repositories and relevant versions

List the repositories needed for the agreed scope. Include application code, supporting services and infrastructure configuration where relevant.

For each repository, identify its owner, the relevant branches, the version deployed to each environment and any private dependencies. Check that permissions support the incoming team's work without granting unnecessary access.

An acceptance check: the incoming team can identify the source version corresponding to the running product. Any uncertainty should be recorded rather than guessed.

3. Verify that the product can be built and run

Collect the required tool versions, installation instructions, configuration requirements and commands needed to build and run the project. Identify private packages, certificates or other prerequisites.

Provide example configuration without secrets. Explain how the necessary values will be supplied through an appropriate secure channel.

Ask a developer who did not write the instructions to follow them. Record missing steps and dependencies. A successful local build is useful evidence, but does not by itself prove production readiness.

An acceptance check: the agreed version can be built and run in the specified environment using the documented procedure, with any exceptions recorded.

4. Inventory environments, accounts and access

List the environments and services involved in the product: hosting, databases, monitoring, app distribution and other relevant systems. Record account ownership, billing responsibility and the contact who can grant access.

Use individual accounts and appropriate permissions where supported. Do not place passwords, tokens, private keys or production data in a checklist, Trello card or ordinary project brief.

Agree how access will be granted, tested and later removed when it is no longer required. Handle credential changes through the responsible team and its established security process.

An acceptance check: required access works for the agreed responsibilities, and account ownership is understood.

5. Document dependencies and integrations

List external APIs, libraries and services that the product relies on. Include documentation locations, relevant versions, service owners, support contacts and the availability of test environments.

Identify dependencies tied to a particular provider's account or licence. These may need separate arrangements to maintain continuity.

For important integrations, explain the supported operations and known failure behaviour. If details are unknown, assign investigation rather than inventing an explanation.

An acceptance check: the incoming team knows the main external dependencies, their owners and the gaps requiring follow-up.

6. Transfer useful documentation and known issues

Prioritise information that supports maintenance: a concise architecture overview, important user journeys, key data flows and operational procedures.

Include known defects, limitations, workarounds and unfinished work. Distinguish confirmed problems from areas that merely need investigation. Mark outdated documentation so it is not mistaken for current behaviour.

A handover does not require every document to be rewritten. It does require important gaps to be visible.

An acceptance check: the incoming team can explain the main components at the level required for its work and locate the current issue backlog.

7. Explain testing and release procedures

Document how changes are checked and how releases reach users. Include automated checks, manual test steps for important journeys, approval requirements and responsibilities for release accounts or signing.

Record rollback or recovery arrangements where they exist. If no procedure exists, make that gap explicit and decide how it affects planned work.

An acceptance check: the incoming team can describe the release path and identify what still needs to be verified. A live release should only be performed when separately agreed and appropriate.

8. Record open items and accept the transition

Use a shared register for gaps. Each item should have an owner, next action, target date and explanation of its effect on the work.

Not every gap must necessarily be resolved before a transition. The product owner and responsible teams should agree which are blocking, which can be accepted temporarily and what follow-up is required.

Acceptance should record what was verified, what remains unresolved and when responsibility changes hands. Avoid treating a folder upload or access invitation as proof that the entire handover is complete.

Copyable handover register

Suggested statuses: Not reviewed; In progress; Verified for agreed scope; Blocked; Not applicable; Accepted with an open item.

What to prepare for an introductory conversation

You can begin with a high-level description of the components, current provider arrangements and the reason for the transition. Identify the materials that exist and the questions that remain open.

You do not need to disclose confidential product details in a public discussion. Arrange appropriate confidentiality and access conditions before sharing protected material.
