'merge requester' name changes to 'Administrator' while Exporting a project and its data to new GitLab instance

I am trying to migrate projects from gitlab.com to one of my self-hosted GitLab instance, for this i’m following the official documentation for Export a project and its data.

Issue: Once we import the .tar.gz project backup to our self-hosted GitLab instance via the project import option, we see some changes in the name of the merge requester found under the section Merge requests.

In Merge requests, the details regarding the “merge requester name” is getting overwritten by the user who is importing the projects to the self-hosted GitLab.

is there any way we can keep the merge requester name the same as in the source GitLab account?
