Multiple Appium versions

Hi There,

Am thinking of creating an appium test environment. For this I want to have two different versions of Appium (apk) on the same mac.

Although this works there is a slight hitch. Both versions seem to share the same properties. I.e. if I change the properties for one version of appium, it is also changed for the other version of appium. Can anyone point me to the location where the properties for appium is stored, and if it is possible to encapsulate the properties of each version?

Regards,
