[otrs] installing itsm on top of existing otrs 2.2

i just upgraded our otrs installation to 2.2, and now i want to give the itsm module a try. but i was wondering why i dont see the itsm packages in the package manager. am i correct in assuming that itsm is just another module (like faq, calendar, etc.) that i can add to my existing otrs without breaking it? -- Mike Conigliaro ProActive Technologies conigliaro@getproactivenow.com 203.239.0440 ext:317 www.getproactivenow.com
