Migrate from Nexus 2 to RepoFlow

Overview

Nexus Repository 2 migrations can be simple when you validate early and keep the cutover window short. The biggest source of surprises is usually a hidden client that still points at a Nexus URL. This guide follows a safe plan and references the RepoFlow CLI migration flow for the transfer step.

RepoFlow CLI migration supported package types

The RepoFlow CLI migration flow currently supports migrating these package types from Nexus 2:

• npm
• NuGet
• Maven
• RubyGems

Why migrate to RepoFlow

• Consolidate package types, manage multiple package types in one platform.
• Keep endpoints simple, replace Nexus group URL patterns with virtual repositories.
• Choose your deployment, use managed cloud or self hosted deployments.

Migration steps

1. Inventory repositories and clients: List hosted, proxy, and group repositories, then find every CI job and script that references Nexus endpoints. If you use group URLs, note which ones need a replacement.
2. Create the RepoFlow repository layout: Create the local, remote, and virtual repositories you need. If you rely on a single Nexus group URL, use a RepoFlow virtual repository so clients can keep one stable read URL.
3. Dry run a representative repository: Migrate a smaller repo with real usage patterns using the RepoFlow CLI migration flow.
4. Validate in CI: Point a single pipeline at RepoFlow and run a clean build that restores dependencies from scratch.
5. Cut over with a short write freeze: Freeze publishing to Nexus 2, run the final sync, then switch endpoints to RepoFlow.
6. Keep Nexus read only while you monitor: After a stable window, archive and decommission safely.
