I was using Gitlab 7.10.4. I created a backup using the following command :
# I have installed GitLab with the Omnibus package
sudo gitlab-rake gitlab:backup:create
Then I tried to upgrade to the lastest Gitlab version (eg. 8.3.4) using :
sudo apt-get update
sudo apt-get install gitlab-ce
For an unknow reason, this has failed. So I had to install a fresh install of Gitlab, but I don't understand why my old backup can't be installed on the new version of Gitlab which generates a version mismatch error.
How to keep my old data backup and upgrade to the lastest version of gitlab ?
