Redmine and gitlab repositories

hello,

I use actually redmine as a project server, and I can access to many repositories
housed on gitolite,
It is easy to configure, (git clone and git fetch) and users appreciate the service.

I would like to move my repos from gitolite to gitlab and build the same collaboration
between the project server and the git server,

Is it possible to do it and how ?

Thank you for your answer,
plap
