Before OTRS 4 there was a file UPGRADING.md containing step by step upgrade instrctions.
Actually (since version 4 afaik) this file contains a link to the upgrade instructions: http://otrs.github.io/doc/manual/admin/4.0/en/html/upgrading.html There is no "single command" or "single step" upgrade in Linux, even if you use a package manager.
