Upgarde from an old Installation

[MysticJ]

Hi,
I have been assigned a terribly outdated CMS installation, based on V1.11.8 with
PHP 5.4.15 and
MySQL 5.5.68-MariaDB

Sure updating it to the latest is one of the first tasks, but
What intermediate versions should I use?
What about PHP and MySQL They likely need to be migrated too in between.

So I am looking for a path like 1.11.8 -> 1.12.1 -> 2.0.1.1-> 2.2 or if possible 1.11.8 -> 2.2.16

Need to keep in mind that for MySQL and PHP I might need to address the hoster.

Thanks for your advise.
M.
