NPM has recently introduced @scopes / organizations for the modules. Is there a good way to migrate existing modules to the organization? Are there any tools for automating it
Another way to do this that doesn't involve renaming the package, is to go to the team settings in your organization on the npm website (there's a default team called "developers"). There's a button there to add an existing package to the team.
This way you actually transfer the package, instead of republishing it under a different name.
