Survey solutions uses case

In a local installation of the survey solutions server, is it possible to install multiple instances on the same web server, for example if I wanted to have another survey run concurrently on the same server with different administration and different interviewers would I need a different environment or is it possible to do it on the same system. also if this is possible can I have multiple instances of the database installation on the same server as this is done within the installation by the installer automatically

I’ve heard negative experiences of users trying to setup multiple instances of Survey Solutions server components on the same server machine. Even if you manage to configure at some point, subsequent updates or backup/maintenance work may wreck that nimble equilibrium.
