Project export / import, with build artifacts

I have the requirement to move number of gitlab projects from one instance of a self-managed Gitlab (v16.6) to another self-managed instance on another server. All data should be preserved/cloned, specifically also the build traces and artifacts.

Gitlab allows to export/import projects, both from Web UI and via API, however there the build traces/artifacts are not migrated (documented restriction).

Is there any other way to accomplish this so I dont loose the build traces/artifacts.
What I noticed is that import/export also does a renumbering of job executions, so you cant match it
between instances.

Thanks for any Help
