Re: Recover a MySQL database from files after upgrading to new version of XAMPP

[Peter Brawley]

Now you've learned to always backup.

I think XAMPP 7.1 and 7.2 both use MariaDB 10.1.36, so MySQL version shouldn't be an issue.

If you're using InnoDB, you may try bringing down the server, moving the InnoDB log files to another location, then restarting MySQL. That will force InnoDB to rebuild its logs. If you're using a MariaDB storage engine, you'll need to ask on the MariaDB forum.

Otherwise, we'll need to see the exact MySQL error messages.
