I tried the following and it worked ..
This is assuming you went through the upgrade process once already ...
Take no responsibility for lost or corrupted data as a results of my post

• stop httpd and gitlab
• Removed /home/git/gitlab [or rename it to _old]
• cloned the gitlab repo again with 5.0 branch
• updated to the correct properties (gitlab.yml, database.yml, unicorn.rb)
• sudo gem install charlock_holmes --version '0.6.9'
• sudo -u git -H bundle install --without development test postgres --deployment
  -- if you run [grep -r "gitlab/gitlab/" *] it should return no result
• sudo chown -R git /home/git/gitlab/log/
• sudo chown -R git /home/git/gitlab/tmp/
• sudo chmod -R u+rwX /home/git/gitlab/log/
• sudo chmod -R u+rwX /home/git/gitlab/tmp/
• sudo -u git -H mkdir /home/git/gitlab/tmp/pids/
• sudo chmod -R u+rwX /home/git/gitlab/tmp/pids
• start httpd and gitlab
