When trying to move a project from one subgroup to another subgroup (within the same group), I get the error message You can only transfer the project to namespaces you manage. I don’t understand why I get this message since I have owner rights on both subgroups (the source and the destination subgroup) as well as for the project itself.
I found out that I can transfer the project to any subgroup I created on my own. For subgroups that were created by other users (but I got owner rights too), the behavior described above occurs.
GitLab Version: Enterprise Edition 10.2.3-ee
Is this a known behavior? Are there any known workarounds?
