Hello,

we plan in our company to inquire some Artefact-Servers (Nexus, Artifactory, Archiva) to our new nexus 2.12.1-OSS-Server and I was thinking that is the best and easiest way to start with the Migration from an old nexus-2.11.4-Server to our new Server. At this point I pack the repositories I would like to migrate in the working directory of the old nexus-Server and unpack it in the new working directory but the new server didn't find the new repositories. That's why I have the question is there a documented way to migrate a Repository from one nexus server to another and of course from other artifact-Servertypes to nexus?

I would be for every hint very thanksful.
best regards
Dan

The docs [1] covers migrating from Archiva and Artifactory to Nexus.

Hello Aders,

the links helps a lot thank you. Maybe do you know a way to migrate from one nexus server to another too?
best regards

There used to be a blog post from Sonatype on this, but the link returns a 404 so it seems it has been lost unfortunately.
AFAIK it should work by copying the sonatype-work folder to the new server. As it contains config etc, Nexus will perform an upgrade if you then (on the new server) start with a newer version of Nexus.

If Nexus can't find the sonatype-work folder there must be something wrong in the nexus config. The most simple solution would probably be to keep the setup from your original installation, for which I assume you have documented any additional config you've done.

Yes this post I found too and I try to copy a single Repository from one server to the new one but this don't work. Now I hope the is a function to "check" the working directory for new repository and add them to the others. Because the Problem is we have to merged multiple nexus Servers to the new one....

The migration chapter in the documentation also covers this.


and there are a couple of videos that demo it from Artifactory and Archiva as well that I recorded a while ago

They are part of the Tips from the Trenches series at 



Note that this approach applies to 2.x versions. 

For 3.x we have built a migration tool from 2.x that will be released soon and we plan to expand it to be able to pull in folders directly.

In the mean time I have an open source tool that can pull dependency trees from on repo (or repo server) to another. It could be expanded easily to pull in a repository on disk since it does exactly that during the dep tree process. You can find it here

Also .. if you need to merge multiple repositories e.g. from multiple repository managers the easiest is to migrate the repository as they come and then use repository groups to manage them as a new unit.
