We have an existing 7.2 installation and I would like to test using Good Dynamics. I understand 7.2 does not support Good Dynamics so I would like to install something that does. Would I go with 7.4? Also I don't want to impact my 7.2 environment. Can I install 7.4 on the same server? If so, are there instructions for this that would allow me to copy and upgrade everything existing for 7.2 but not not change the existing 7.2 installation? Thanks!
