I'm working on a program to migrate multiple repos from a git server to a Gitlab one. The migration part is already done and now I want to check if everything went okay and that all the repos were migrated properly.
What is the best way to do that ?
Clone the code from gitlab
git clone <gitlab-repo-url>
Add the git server repo url as a remote on your local repo
cd <repo>
git remote add oldserver <git-server-repo-url>
Run git fetch for both remotes
git fetch --all
Run git log showing commits from all your remotes
git log --decorate=short --oneline --remotes=* --branches=*
If you see both remotes master branches pointing to the same commit, it's a strong indicator migration went well
