Code migrations coordinated across every repo

Large migrations should not consume months of engineering coordination. Rosvelt maps the change across repos, rewrites the code, fixes broken builds, and ships isolated completed work for review.

Problem

Large migrations are too big for normal sprint work and too nuanced for simple codemods. Teams get stuck coordinating repos, fixing edge cases, and babysitting broken builds across the entire codebase.

How it works

Agents run the migration for you

Define the target architecture once, and Rosvelt turns it into coordinated, repo-by-repo migration work with build feedback, tests, and isolated completed work for review.

3Capture the migration as a ticket: the pattern to retire and the target to reach.

4Rosvelt scopes the work and maps every affected file and repo.

5Agents rewrite the code, run builds and tests, and fix what breaks.

6Each repo ships as isolated completed work for review with a live preview.

Tickets

Track scoped work, ownership, progress, blockers, and review in one board.

What you can migrate

Point Rosvelt at the patterns you want to retire and the target you want to standardize on.

What you get

A migration system that turns months of coordination into traceable completed updates, each with its own checks, context, and review path.

Review before you merge

Rosvelt moves the migration forward, but every repo still lands through your normal review, CI, ownership, and approval process.

Every change arrives as completed work for review in your own repo, with the same review, checks, and ownership you already trust. Read the diff, run the tests, open the live preview, and ask for adjustments right in the thread.

Preview

Inspect the result, request edits, and move it forward without changing tools.

Why it's different

A scripted codemod stops at "it compiled"; Rosvelt owns the change until it actually works.

With Rosvelt

Maps and migrates every repo from a single definition.

Runs builds and tests, then fixes the fallout.

Ships completed work for review you can iterate on in a thread.

Doing it yourself

Write and babysit codemods for every edge case.

Chase broken builds across dozens of repos by hand.

Redo the whole effort when the next version lands.
