Application / Database Move to new Drive

Greetings,

In testing out the AD Audit Plus trial version, the server it current resides on was built with a production standard name, but non-production standard format on where the application is installed.

As it currently resides on the boot partition (C:), now that we've procured licensing for the application, I'd like to move the application and Postgres database from its installation on C: to D:.

Is this possible without reinstalling the entire application? Or losing what data the database already contains?

I did find some links to move the entire installation to a new server, so that may be the best/only idea. Or building a new box, and migrating the application over to it after the new installation is stood up.

Please let me know if anyone has any thoughts on this when you can. Thank you.

Jeff
