I am having data of 20 GB with MySQL version 5.0.24.
Now I want to update MySQL to newer version 5.5.16.
We can do it by taking complete database backup and uninstall old MySQL and install new MySQL and restore database.
But, Is there any way to upgrade MySQL directly to newer version, as it is a production setup and wanted very less down time of the server.
Please help me on this.
I am running on Windows.
