I have a question, is this possible to install on the same machine windows server 2012 two services AdselfService and Servicedesk? I have already installed AdselfService and now want to install Servicedesk,

as I see these services working on different web page ports 8888 versus 80/443, but what about shared database I have then one instance of Postgresql but with two separare databases, one for AdselfService and another to Servicedesk?

Please explain me this, thank you.
