Migrate GitLab 7.7.2 server


Hi, I appreciate you can help me with some questions, I have GitLab 7.7.2 I need to migrate it from server, on the Internet it is mentioned that the new server must have the same version of GitLab to migrate, they mention that GitLab must be updated with yum update gitlab-ce in the old server, I’m afraid the update could damage the production server, how can I install version 7.7.2 of GitLab to run a test lab before running the gitlab update with yum update gitlab-ce in production?

Thanks for your help
