I Think that you can have both instaled the OLD and the newer version. Can be tricky, but you will have less downtime and nearly seamless migration. Andres Paul POULAIN wrote:

I think 4.0 is a minimum for sure. For example, 3.23 doesn't include query_cache so everything runs _very_ slowly. I've not tried out 4.1 but I'm not against it as a minimum. Since MySQL AB releases official RPMs for all version of MySQL, it's not too hard to install a newer version on RPM-based systems.
Not so easy : binary format of mysql databases differs from another version to another one. So, once you've installed a version X & have some DB, it's quite not so easy to update, because you have to dump everything, delete everything, install mysql X+1, and reload databases.
