4.2.0 upgrade question regarding MySQL

Hi all,

I'm in the process of attempting to upgrade 4.2.0 to 4.2.3 using the autodeploy script when it shows me this:

It appears that the distro-supplied version of MySQL is at least partially installed,
or a prior installation attempt failed.


Please remove these packages, as well as their dependencies (often postfix), and then
retry this script:


MySQL-shared-5.5.28-1.linux2.6.x86_64
MySQL-server-5.5.28-1.linux2.6.x86_64
MySQL-client-5.5.28-1.linux2.6.x86_64

My current Zenoss is running without issue now, I don't think it's wise to blow away my existing MySQL to satisfy this script.  Help?

Thanks!
