I would like to downgrade MySQL 8 to MySQL 5.7 on centos 8, can I get the proper steps/commands. Thanks in advance.
Downgrade from MySQL 8.0 to MySQL 5.7, or from a MySQL 8.0 release to a previous MySQL 8.0 release, is not supported. The only supported alternative is to restore a backup taken before upgrading. It is therefore imperative that you back up your data before starting the upgrade process.
