As already said: there is no "upgrade" from one CentOS Linux major version to other. Always a fresh install.
PS. If you mean CentOS Linux 8 with the "CentOS 8", then you should have noticed that CentOS Linux 8 will be dead at the end of this year. Consider some other OS.
Because it will break. And it's explicitly unsupported and if you try it and it breaks (which it will) then you get to keep all of the pieces.
