Gitlab 7.4.2 Installation package

Hi, I have some backups from our old Gitlab 7.4.2 server. This server has been out of use for some time, but I would like to install gitlab and restore the data, so I can update it to current version to start using it again. I cannot seem to find a copy of 7.4.2 - can anyone help? Or if not, is there any other way to get this data onto a newer version of gitlab?
