The command to use here would be rpm -Uvh, as these packages are not in
the yum system.
You would need to uninstall the current mysql first, however - and to
migrate any data, you need to use mysqldump --all --opt before that, and
then import it back after 5.x is installed.
Last time I checked, you could not use the same database files for
different major versions of MySQL - I could be wrong on this point, however.
