Hi,
The transfer of databases between different versions of MySQL or MariaDB should be performed by EXPORT / IMPORT of SQL files using phpMyAdmin or a similiar tools of your choice.
Do not copy the data folder between different versions of MYSQL. Databases from different versions of MYSQL are VERY unlikely to be compatible! You will also destroy the version of MYSQL that you copied the data folder to.

There is no my.cnf file with Wampserver.
The correct file is my.ini :
Left-Click Wampmanager tray icon -> MySQL -> my.ini
And the contents of datadir must be enclosed in quotation marks "..."
