Unity 2018.04.16f and Oculus SDK versions

Hi

I'm currently trying to port a VR project built in Unity 2018.04.16f for HTC Vive for Oculus Quest 2. I'm currently running into issues regarding Oculus SDK version being incompatible with my Unity version and replicating the VR interactions in HTC Vive build for Oculus Quest 2.

Can I please get some guidance or tips on this issue?

Thanks
