A full-featured RDBMS is not just a set of files that can be moved around. It's a complicated beast.

About direct file copy, see that topic under "file snapshot" at https://dev.mysql.com/doc/mysql-backup-excerpt/5.7/en/backup-methods.html

Trying to transfer data directory contents between versions is pretty much guaranteed to fail.
