Hey, I am not sure what the comment mean here. It may mean that they cannot downgrade a mysql 8.0 db to mysql 5.7 db (migrating all the db data into a older version db). Because phpmyadmin doesn’t support mysql 8.0. So What I did is running a older version of mysql. I started a new empty db instance. Instead of mysql-8.0.11-winx64, you need to install mysql-5.

Note:
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.

I already have Apache 2.4.33 Win64, php-7.2.5, mysql-8.0.11-winx64 and phpMyAdmin-4.8.0.1 installed and getting the following error:

Cannot log in to the MySQL server

mysqli_real_connect(): The server requested authentication method unknown to the client [caching_sha2_password]

mysqli_real_connect(): (HY000/2054): The server requested authentication method unknown to the client

How do I downgrade mysql-8.0.11 to a lower version?
