DepMigrate – AI-Powered Framework Migration Agent

Inspiration

Modern software evolves rapidly, but upgrading dependencies remains one of the most painful tasks for developers. Every major framework release introduces deprecated APIs, breaking changes, and migration guides that developers must manually read and interpret. Teams often spend hours searching documentation, changelogs, release notes, and GitHub discussions just to understand what needs to change in their codebase.

We wanted to eliminate this friction by creating an AI agent that acts as a migration expert—automatically understanding framework evolution and guiding developers through upgrades with confidence.

What it does

DepMigrate is a GitLab Duo Agent that helps developers migrate away from deprecated packages and APIs with minimal effort.

The agent analyzes project dependencies, identifies deprecated libraries and framework APIs, researches official migration documentation, scans the codebase for affected usages, and generates an actionable migration plan.

Unlike traditional upgrade tools that simply flag outdated dependencies, DepMigrate understands the semantic changes between framework versions and explains exactly what developers need to update.

Key capabilities include:

  • Detecting deprecated packages and APIs
  • Understanding official migration guides and release notes
  • Finding affected code across repositories
  • Classifying migration complexity and risk
  • Generating migration recommendations
  • Applying safe automated code transformations
  • Creating merge requests with detailed migration reports
  • Keeping developers in control through human approval checkpoints

How we built it

DepMigrate is built on the GitLab Duo Agent Platform and leverages GitLab's repository context, code search, commit history, and workflow automation capabilities.

The agent follows a multi-stage migration workflow:

  • Dependency Analysis – Identifies deprecated libraries and outdated packages.
  • Documentation Intelligence – Collects and analyzes official migration documentation.
  • Code Impact Analysis – Finds all usages of deprecated APIs within the repository.
  • Migration Planning – Generates a structured migration roadmap with risk assessments.
  • Human-in-the-Loop Approval – Presents the migration plan before any code changes occur.
  • Automated Refactoring – Applies targeted code modifications where safe.
  • Merge Request Generation – Creates a reviewable merge request with explanations and change summaries.

By combining repository intelligence with AI-driven documentation understanding, DepMigrate transforms migration work from a manual research task into an automated workflow.

Challenges we ran into

One of the biggest challenges was ensuring migration recommendations remained accurate and trustworthy. Documentation is often scattered across release notes, migration guides, changelogs, and issue discussions.

Another challenge was balancing automation with developer control. Fully automated migrations can be risky, so we designed the workflow around human approval checkpoints to ensure developers remain in control of every change.

Accomplishments that we're proud of

Built an AI agent focused on a real developer productivity problem. Created a workflow that goes beyond dependency updates and understands framework migrations semantically. Integrated migration analysis directly into the GitLab development workflow. Designed a human-in-the-loop migration experience that prioritizes safety and transparency. What we learned

We learned that dependency upgrades are not simply version bumps—they are knowledge problems. Developers spend more time understanding changes than actually implementing them.

By combining repository context, documentation intelligence, and AI reasoning, migration workflows can become dramatically simpler and more reliable.

What's next for DepMigrate

Future versions of DepMigrate will support:

Framework-aware migration intelligence for React, Next.js, Angular, Vue, FastAPI, and more Automatic migration risk scoring Repository-wide impact analysis Codemod generation CI/CD migration validation IDE integrations Continuous dependency monitoring Organization-wide upgrade recommendations

Our long-term vision is to build the definitive AI migration assistant that helps engineering teams upgrade software safely, quickly, and confidently—without spending days reading documentation.
