To fix problem with cPanel / WHM upgrade if:
error: Failed dependencies:
MySQL conflicts with mysql-5.0.x
Read: http://docs.cpanel.net/bin/view/AllDocumentation/InstallationGuide/RPMTroubleshoot and forum posts http://forums.cpanel.net/f5/case-64049-overnight-update-failed-mysql-conflicts-mysql-5-0-77-4-el5_4-2-i386-320381.html
Made all MySQL databases backup and run command as root user:
# rpm -e –nodeps –allmatches –justdb mysql-5.0.x
It will resolve Conflict With Rogue mysql RPM.
Run cPanel / WHM update once again.
