MySQL4 > MySQL5 upgrade

Hello, has anyone attempted to upgrade their MySQL4.x to MySQL5.x? I have a few websites on my server which runs Apache2.2, PHP5 and MySQL4.1 and I need to upgrade/install MySQL5.0, will I encounter any problems, anyone here that can share experience with this? :)

I'm thinking I would need to deinstall the 4.1 and then install 5.0, will the data (users ,passwords, databases) be kept intact?

Thanks!
