Migration Agent
Capabilities
What this agent does
Every capability is shipped end-to-end — not a feature flag. You get a working slice on day one and we expand from there.
Feature 01
Bulk codemod runs
AST-aware transformations across thousands of files.
Feature 02
LLM cleanup
Handles the cases mechanical codemods can't.
Feature 03
PR per module
Splits work into reviewable chunks, not one mega-PR.
Feature 04
Compatibility shim
Generates adapters when API surface changes.
Feature 05
Rollout dashboard
Tracks % migrated, broken tests, blocking issues.
Stack
9 technologies we use
Production-tested tools chosen for reliability, observability, and developer velocity. Every piece is swappable.

How we roll it out
A 5-step process from kickoff to handover. Every step has a deliverable you can sign off on.
- 01
Target survey
Map current versions and dependency graph.
- 02
Compatibility map
Identify breaking changes between old and new.
- 03
Pilot module
Migrate one isolated module to validate the playbook.
- 04
Rolling PRs
Module-by-module PRs with shared infra branch.
- 05
Cleanup sweep
Remove shims and deprecated paths after full migration.
Outcomes
What you can expect
Real numbers we see when Migration Agent ships on top of an actual workflow. Specifics vary with starting baseline, data quality, and scope — but these are the ranges.
Outcome 01
−35%
PR cycle time
Reviews land in minutes; trivial issues auto-fixed.
Outcome 02
+40%
Bug catch rate
Pre-merge, vs the previous review process alone.
Outcome 03
−50%
MTTR
Mean time to resolve incidents after agent investigates first.
Sample use cases
What this looks like in practice
Three concrete scenarios where teams deploy Migration Agent today. Your engagement starts with one of these (or your own variant) and expands from there.
Always-on senior reviewer
Every PR gets an inline review for bugs, security, breaking changes — junior engineers ship safer code, seniors spend review time on architecture.
First-responder on every page
When PagerDuty fires, the agent correlates logs + metrics + recent deploys, drafts the incident summary, runs read-only diagnostics, posts to Slack.
Migration at scale
Framework or major-version upgrade across hundreds of files — agent applies AST codemods, fixes the edge cases LLM-style, opens reviewable PRs per module.
Typical engagement
From kickoff to live in 4-8 weeks
Most Migration Agent engagements follow this shape. We give you a firm quote after a 30-minute scoping call, and the price is fixed up-front so you can budget.
