Publish package versions from one registry into another.

Setup

npm install npm run build

Using the script

node ./dist/cli.js --name @scope/pkgname \
 --from.registry https://registry.npmjs.org/ --from.token $NPM_TOKEN \
 --to.registry https://npm.pkg.github.com --to.token $GITHUB_TOKEN

This will migrate all the versions that it can find on the "FROM.REGISTRY" that are missing on the "TO.REGISTRY"

If new versions of the package are published to the ORIGIN registry, they'll need to be migrated again in the future.

I'td be best to ensure that the package you're dealing with is automatically published to the new registry as part of its CI process.
