Question Upgrading from v11.5.30

[CyberShadow]

I am using CentOS, running a VPS with root access.
It seems that my version of Plesk isn't automatically updating. When I go to the settings page, there are no links to allow me to upgrade my version of Plesk. I consulted with my host, and they suggest that because the version that I am using is so old (v11.5.30) I will need to upgrade via SSH. If I go ahead with this, can I directly upgrade from v11 to the current version in one step, or is it better to upgrade to a mid-point first, and if I do find a mid-point, will this open up the ability to upgrade automatically via the Plesk panel?

In general.... Any advice for upgrading from v11 via SSH?
Thanks.

You can upgrade to Plesk Obsidian from Plesk Onyx 17.0 and later. See if your OS is supported.
If you use Plesk 12.5 or earlier, upgrade to Plesk Onyx first.

Many thanks. I am running CentOS 6 so it looks like I am well supported to go ahead with this.
