we have some npm artifacts on a nexus 3 installed server A 
we have some npm artifacts and all of the maven artifacts on another server B

we would like to bring the artifacts on server A to server B. 

is there a simple way ? 

i think i remember that the only way suggested was to leave the old server A running and point it as proxy from the server B once the cache gets all the artifacts then safely remove the server A. 

any help or pointers appreciated. 

Thank you in advance for your time.

This is a way I could see you doing this:


Run that script to list all assets in your npm repo and then use curl to download them to a local folder.


You can use the npm import script from there to push stuff in I believe.

These are community scripts (the second one I wrote), so your mileage may vary, but this might work for you. Let me know how it goes?

Other potential paths forward:
- haven't tried this, but presumably it works and is easy to use with your existing npm toolchain? https://www.npmjs.com/package/npm-copy
- you can set up a proxy of server A on server B and proactively request all content to populate the proxy Repository using the existing (beta) REST api. i.e. Iterate over all npm files exposed from server A through the REST api and then request those same packages from server B so your proxy eventually contains all of the same packages. Details of the REST api are documented at http://{nexus host}:{nexus port}/swagger-ui/#!/assets/getAssets

Note that any of these approaches we've discussed are going to have some data changes in terms of publish date, etc., but that shouldn't have any impact on using these packages with npm.

Does anyone know if it is possible to convert a proxy repository to a hosted repository?

Hi Mariska,

I asked this question before, unfortunately the answer is... no :-(

What is the need for converting it to a hosted repo?

If the remote site is no longer available, and you don't want Nexus to check for it, but still need the components available, you can set the Proxy repo to "Manually Blocked".

The need would be to support a complete migration and end up with only one hosted repository instead of a new hosted repository and a proxy repository which is a mirror of the old instance. But your solution will also work. Thanks.

Had the same situation - needed to migrate artifacts to another machine (Nexus 3 OSS to Nexus 3 OSS) and came up with the following: https://github.com/metallaw/scripts/blob/master/nexus_copy_artifacts.sh
