This article explains whether it is a good idea or not to install WPM on the same server as other Orion products and why.
All versions of WPM
Generally, it is preferred to install WPM on the same server as other Orion products. All Orion products are designed to be fully compatible with each other and work together. This makes it easier for customers as it means fewer databases and servers to set up.
However, it is a good idea to verify that the version of WPM you are installing is compatible with the versions of the other Orion products you have installed. New version of WPM may not be compatible with older versions of Orion products.
