Updating from 7.4.3 on Debian


I have inherited an omnibus installation of gitlab 7.4.3 for Debian 7 and would like to bring this upto the latest version.

I noticed that the package that is installed on my system is called ‘gitlab’ and not ‘gitlab-ce’. Why the difference?

Is the update as simple as as:

sudo apt-get update
sudo apt-get install gitlab-ce

and will this preserve my existing repositories?
