Repository Management with Nexus
Chapter 22. Migrating to Nexus
If you have been running another repository manager, such as Artifactory, Archiva, or Proximity, and you want to migrate this repository to Nexus, you can do so by copying the files from a standard Maven 2 repository file layout to Nexus.
Depending on your repository managers you will have to use different approaches to get access to a repository in Maven 2 format on disk.
Nexus stores it’s artifacts in standard maven 2 layout, and they are served directly from disk, and can therefore be easily integrated into an existing Nexus instance as a new hosted repository.
