This page will help you with the major changes made to operating RenderMan in Maya. RfM2, as we call it, has been extensively re-written to avoid redundant menus, reduce the number of clicks you need to make, and present RenderMan options as native Maya menu items. This means users can jump right into RenderMan with what they already know.
Many options have been removed from RenderMan or simplified, these decisions were to improve performance of the renderer and the workflow for artists, as such, the options provided are to help guide the user to the correct workflows and reduce headaches. As always, avoid using optimization controls (like those found in integrators and some materials like PxrVolume) to achieve a specific look. These techniques may be improved or modernized in later versions and you will not have access to them.
Please note that the original RMSTREE variable is no longer used and instead we We use RFMTREE for the Maya plugin environment variable. You can find details here.

The following python script can correct these or they can be run individually depending on your scene's needs or included features from RenderMan 21. We do not run this script on import to avoid performance problems loading large or complex scenes. Instead these are provided to the user to use as needed.
