Updating gitlab from 10.5 to 11.4


i have a Centos 7 server with gitlab 10.5 installed and are about to update the whole machine with yum update.

yum list installed|grep gitlab
gitlab-ce.x86_64 10.5.6-ce.0.el7 @gitlab_gitlab-ce
gitlab-ci-multi-runner.x86_64 9.5.1-1 @runner_gitlab-ci-multi-runner

I did some research about updating gitlab and found multiple articles about it:
a simple one:

that states that i just need to backup and run yum install gitlab-ce.

on the other hand i have found also more complex update procedures:

The question is if i can update gitlab with yum only. Do i have to do the DB update manually? Also is it ok to go from 10.5 to 11.4? or should i first go to 10.8 and then in a second step to 11.4?
