[CentOS] Least painful MySQL 4.1 -> 5 upgrade on CentOS 4.1

Hi. I've happily been running MySQL 4.1 on my CentOS 4.1 x86_64 server. 
But I need to upgrade to MySQL 5. Any recommendations on how to 
accomplish this without too much pain? I guess I'll need to get RPMs 
from the MySQL website.

Br,

Morten
