Installation of multiple versions of the Interviewer app on a single Server

Good morning,

Is it possible to install two different versions of the Interviewer App on the same Server?

Interviewer application is an integrated part of Headquarters application.
Interviewer is installed on Android device and communicates with server Headquarters application.
Headquarters application could be configured to work with the previous versions of Interviewer application if Headquarters is upgraded.

Thank you for your response.
