[otrs] Upgrade steps from 2.3.2 to 2.3.4?

Hi there, I see that there are upgrade instructions fro 2.2* to 2.3* but what about 2.3.2 to 2.3.4 Are there any special considerations. I would assume that it wouldn't be a simple as dragging the new folder in there since I would loose config settings and the likes. Mik
