Import repo from local Gogs server to new local Gitlab server

Hi there!

Gogs Version: 0.11.61.0816

Go 1.10.3

Description

I have task to migrate whole repository from our Gogs server to newly installed Gitlab server!

Before considering to forget my repositories history (comments, issues, etc...), do one know of a way to export a repository data from a Gogs server to Gitlab Server ?

I just failed to found anything on the documentation for exporting/migrating the whole project data (not just the git repository and its wiki).
