Centos 5.11 mysql-server 5.0.95 upgrade to mysql55w-server

Here's my thought process on my upgrade:

mysqldump --all-databases > backup.sql

service mysqld stop

yum remove mysql mysql-server

yum install mysql55w mysql55w-server

service mysqld start

mysql_upgrade

theoretically, I should be good after that right? Anything I'm missing here? I'm scared to death of this upgrade. All the ones I've been reading about are from 5.1 to 5.5, not 5.0.95.

Can someone confirm/deny I'm going about this ok, or am I missing some huge steps?
