Code Migrations
The version bump
is easy.
The migration isn't.
Dependabot bumps the version number. That's the easy part. The hard part is every repo using the old API, deprecated method, or removed import. And needing actual code changes before anything compiles again.
Migrate all services from @redis/client to @upstash/redis. Update imports, remove the manual connect() call, and update method signatures per the migration guide.
The Problem
A routine upgrade becomes a multi-month project
Library migrations aren't a single find-and-replace. They're changed APIs, renamed imports, updated method signatures, and argument reordering, each one subtly different per repo. Dependabot handles the package.json. Nobody handles the actual code.
Your teams find out one by one, mid-sprint, when their builds break. The fix is well-understood. Getting it done across 47 repos: that's the problem. That's what turns weeks of work into months of coordination.
Without Tidra
- Teams handle migrations one repo at a time
- Weeks of coordination across squads
- Inconsistent patterns emerge
- Builds break mid-sprint, feature work stalls
- Senior engineers pulled off roadmap work
With Tidra
- One initiative updates all repos in parallel
- Days from start to merged PRs
- Consistent, reviewable standard enforced
- Teams see working PRs, not first drafts
- Platform team owns it end-to-end
Live Example
@redis/client → @upstash/redis
Every import, client initialization, and method call, rewritten across all 47 affected repos. Not a template. Actual code, adapted to each codebase.
How It Works
From description to merged PRs
01
Describe the migration
Tell Tidra what's changing: the old library and the new one, or paste the migration guide. Tidra understands context, not just string replacement.
02
Tidra scans all repos
It identifies every file using the old API across your entire organization: imports, method calls, config references, all of it.
03
AI rewrites each file
Every import, initialization, and method call gets updated to the new API, in context, per repo. Tidra adapts to each codebase's patterns.
04
Review before merging
Check the diffs. Iterate if needed. Open PRs when you're confident. Teams see working code, not first drafts.
Common Migrations
If it's a breaking change,
Tidra can handle it
Tidra handles migrations where the version bump alone isn't enough. Where actual code changes are required before anything compiles again. If there's a migration guide, Tidra can execute it at scale.

-
Client library migrations
@redis/client → @upstash/redis, axios → fetch
-

-
Internal SDK major versions
Breaking changes rolled out from your own platform team
-
Authentication library updates
passport.js v0.5 → v0.6, NextAuth v4 → v5
-
Testing framework migrations
Enzyme → React Testing Library, Mocha → Vitest
-
ORM and database client updates
Sequelize v5 → v6, Mongoose v7 → v8 breaking changes
-
HTTP client modernization
node-fetch v2 → v3 (ESM), got v11 → v12 API changes
From the library
Example framework migrations
Spring Boot 2 to 3 Migration
Migrate Java services from Spring Boot 2.x to 3.x, Jakarta EE namespace rewrites, deprecated API replacements, and configuration property renames across every service.
Rails 6 to 7 Migration
Migrate Ruby on Rails services from 6.x to 7.x, zeitwerk autoloading, Hotwire defaults, deprecation cleanup, and gem compatibility fixes across every service.
React 17 to 19 Migration
Migrate React apps from 17 to 19, concurrent rendering opt-in, removed APIs (string refs, legacy context), and new JSX transform across every frontend.
Frequently asked questions
What runtime and framework versions can Tidra migrate?
Language runtimes (Node.js, Python, Go, Java), framework major versions, package manager changes, client library migrations, Kubernetes API deprecations, and internal SDK breaking changes. Before writing anything, Tidra reads how each repo is actually set up.
How does Tidra handle repos that need different migration paths?
Tidra checks each repo's package manager, framework version, and existing dependencies before writing anything. If repos are on different starting versions, they get different migration paths from the same initiative.
What about repos that use a library in a non-standard way?
Tidra flags those repos. If it finds custom wrappers, unusual integrations, or usage it is not sure how to handle correctly, it tells you rather than guessing. You review those repos manually or update the plan for them.
Is this different from running Renovate or Dependabot?
Yes. Renovate and Dependabot handle routine version bumps. Tidra handles migrations where the version change also requires code changes: updating API call patterns, fixing type changes, working through breaking changes across files. The two tools do different things.

Your next migration
shouldn't take months
Define the change once. Tidra scans every repo, rewrites every affected file, and opens PRs for your review. You control what ships.
Hours, not months.
