Migrating from MRTK 2.4 to 2.8.3

[EngrMariam]

I have been using Unity version 2019.4.4 with MRTK 2.4, and I’m currently trying to migrate to MRTK 2.8.3. However, I am encountering numerous compiler errors during the process.
Has anyone successfully completed this migration? If so, could you please share any tips or tricks you found helpful? I haven't found documentation specifically addressing the migration from 2.4 to 2.8.3; most resources I’ve seen only cover the transition from 2.0 to 2.4.
