Getting a lot of conflicts when upgrading anaconda to latest version

I ran the command conda install anaconda=2020.11 but got a lot of package conflicts.

Does it mean I have to install anaconda v2020.11 using the installation file since the package conflicts cannot be resolved without risking my current set-up?

I am currently using anavonda 2020.07
