How to migrate plugins

I have been asked to migrate a project from 4.2 to 5.2. The project uses the PhysXVehicles plugin, which has been depreciated in favor of Chaos. Am I supposed to add Chaos to the 4.2 version or PhysXVeichles to the 5.2 version before converting assets? If its add PhysXVehicles to 5.2, how do I do that, the project wont launch to give me access to the plugins menu without PhysXVehicles?

Hey there @nweise! Before even attempting to port the PhysX vehicles, you’d likely need to port the old PhysX implementation to UE5. It seems like a user had pulled that part off over in this thread:

However, you’d still have to recompile the old vehicles plugin with the new implementation, which will be lots of source work.
