[otrs] How to upgrade from 2.3.3 to 2.3.4

This is a very basic question, and I don't see any documentation when upgrading minor versions, but how do you upgrade OTRS 2.3.3 to 2.3.4? I only see upgrade documentation for 2.2 to 2.3 in the source file. I'm assuming I back up my current config.pm file and overwrite all files from 2.3.3 with 2.3.4?
