Installing Sitecore 9.1 and Sitecore 9.0.x in the same machine
Sitecore 9 has been out there for over a year now. Sitecore 9.1 has only been around a few months. Many Sitecore geeks would've already tried their hands on both, but not many would've run into the situation where you have to have both Sitecore 9 and Sitecore 9.1 running on the same machine.
