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. -- Cheers, Morten
