Upgrading gitlab from 7.2.1 to 9.2

We are using gitlab version 7.2.1 CE and installed using omnibus installation. Now we are planning to upgrade to 9.2. Already I have referred this below discussions related to upgrade.

  1. Upgrading GitLab from 7.x to 8.x
  2. Upgrade from gitlab-ce 7.10.0 to gitlab-ce-8.15.4 using backup restore

But the official gitlab update page says it is possible to upgrade directly from 6.6 to latest version.

Please let me know the correct update procedure?
After the upgrade using the official update page what are all the steps need to be performed?

Can’t say for upgrade from 7.x but I just did an upgrade from 8.2.1 to 9.5.1. All I needed to do was the following:
apt-get update
apt-get install gitlab-ce=9.5.1-ce.0
gitlab-ctl reconfigure
gitlab-ctl restart

@hozawa, Thanks for your replay. we too able to upgrade from 7.2.1 to 9.2 directly by referring the official gitlab upgrade documentation.
