    Short answer

    Transitioning an active software project from an existing development agency or freelance team to a new engineering partner is a critical operational event. Without structured transition planning, organizations risk losing source code control, missing cloud credentials, breaking production builds, or incurring severe operational downtime.

    A successful vendor transition requires taking ownership of 4 primary asset categories:

    Source Code Repositories (GitHub/GitLab) + Cloud & Server Credentials (AWS/Vercel/Hetzner) + Data & Database Backups + Third-Party API & Developer Accounts (Apple, Google, Stripe) =

    Controlled Technical Handover

    A proper technical handover ensures your internal team retains full ownership, security, and continuity of digital assets.

    Vendor Handover Asset Matrix:

    Asset CategoryKey ItemsHandover Requirement
    CodebaseGit repositories, branches, CI/CD pipelinesTransfer Organization ownership, revoke old SSH keys
    InfrastructureCloud portals, VPS access, DNS managementRotate admin passwords, transfer root billing control
    DatabasePostgreSQL/MySQL dumps, environment secretsSecure database backup, rotate database user credentials

    1. Step-by-Step Vendor Transition Strategy

    #### Step 1: Secure Direct Owner Access to Git Repositories

    Never allow third-party agencies to host your proprietary source code exclusively on their personal Git accounts.

    • Ensure your company owns the GitHub / GitLab Organization.
    • Require developers to work inside your organization repositories.
    • Upon transition, remove vendor access rights, revoke personal access tokens (PATs), and rotate SSH keys.

    #### Step 2: Cloud Infrastructure & Server Ownership Audit

    Verify root administrative ownership across all hosting providers:

    • AWS / Google Cloud / Azure Root Billing Accounts
    • Vercel / Netlify Organization accounts
    • Hetzner / DigitalOcean team accounts
    • Cloudflare / DNS Registrar administrative portals

    Rotate all API keys, access secrets (`.env`), and SSH access credentials immediately after offboarding.

    #### Step 3: Database & File Storage Backups

    Obtain full, unencrypted database snapshots and object storage backups:

    • PostgreSQL `pg_dump` or MySQL `mysqldump` files
    • AWS S3 bucket backups
    • Verify backup integrity by performing a trial database restoration on an isolated test environment.

    #### Step 4: Third-Party Service and Store Accounts

    Transfer primary ownership for:

    • Apple Developer Program & App Store Connect
    • Google Play Console
    • Payment Gateways (Stripe, Iyzico, PayPal)
    • Communication Gateways (Twilio, SendGrid, Resend)

    #### Step 5: Technical Discovery Audit with the New Engineering Team

    Have your incoming engineering team perform a 2-week Technical Audit:

    • Build and run code locally from scratch (`npm run dev` / `docker compose up`).
    • Review code quality, framework versions, and architectural debt.
    • Audit environment variables and hardcoded secrets.

    Vendor Transition Checklist

    • [ ] Audit Git organization ownership and revoke former developer access
    • [ ] Transfer cloud billing and root administrator access to company accounts
    • [ ] Take independent database snapshots and test local database restoration
    • [ ] Rotate all API keys, JWT secrets, database passwords, and SSH keys
    • [ ] Verify ownership of Apple, Google, Stripe, and domain registration accounts
    • [ ] Conduct incoming technical audit and runbook verification
