I am upgrading an existing compactlogix from a L33ER processor to an L37ERM because the system I'm working on needs more ethernet connections. I did not have the original project file so I did an upload from the L33 processor, made a copy and then changed the processor type in the project.
After physically installing and downloading the changed program into the L37 processor none of the VFDs (powerflex 525) that are connected will start. When going online the VFDs are showing that they are connected and I am able to view the configuration, but when given a start signal they do not start. The inputs from the VFDs show that they are ready and not faulted so I'm at a loss.
When swapping back the old processor the system works again as normal. My best guess is this has something do with the old processor using v30 firmware and the new processor using v31. All of the drives are on firmware 5.001. I have around 20 drives total and I'm hoping that I don't have to update the firmware on all of them 
My other guess is it has something to do with the keying of the processor. I used the compare tool and essentially the only difference between the old and the new project is the Ekey state. https://imgur.com/5ou4ATy (new project on left, old project on right) I have no clue how to change this state to match the old project.
Hopefully someone here can lead me in the right direction with this because I'm stumped. Let me know if more information is needed and I can post more screenshots.
