Migrating users between accounts

Is there any way to export users between different GitLab accounts?

I have installed new Gitlab(9.4.2 Omnibus) on new server(Centos 7 OS) and I have the old project on the old server.
I don’t want to migrate the entire project because the web hooks are not written very good and needs to be rewritten, so I cloned only the source code to the new server.

Now I’m searching for a way to export only the users from the old server to the new server.

Any help would be much appreciated.
