Package Manager/XR Manager Issues when Updating VR Project from Unity 2017 to 2020

Hi, currently I’m updating a Unity 2017 VR Motion sickness project to Unity 2020, but a direct conversion obviously hasn’t worked. I have over 50 error messages from the package cache, saying that certain types are found in two areas, all within com.unity.collab-proxy@1.3.9. There’s a couple xr.management issues as well, pertaining to types found twice. Additionally, I’ve tried to install the XR Manager, and while it says I’ve installed it, the tab for it in project settings has disappeared. Does anyone have any recommendations? Thanks in advance.

Have you restarted Unity? It took me a couple of restarts (3 I think), with one or two things set right each time, then it was gone and finally all settings was ok. But I upgraded the project from 2019.1… Then I could manually fix the camera and other things.


Update: This is what it looks like in my Oculus Quest project. Especially the settings to the left was hard to get in place and when I checked the Oculus plugin it didn’t take and I restarted, and somehow finally it was like in the image.
