Migrate from Github to Gitlab

I recently migrate from Github to Gitlab.
What is the easiest way to change my packages urls from Github to Gitlab?
And how can I release new versions from Gitlab? In Github there is Registrator.jl robot. As far as i can see, it won’t in Gitlab…

(only second and third points apply)

My understanding is that the registrator in JuliaHub is the only option for GitLab users to do automated registrations
