Cause
The appropriate jdbc driver (in this example the MySQL jdbc driver) has not been installed or copied from the old instance.
Resolution
Copy the jdbc from your old installation to your new installation, or download the latest driver from the manufacturer's website. The driver can be found either at common/lib directory or confluence/WEB-INF/lib directory.
For MySQL, please see the complete list of steps to download and install the JDBC driver in this page.
