install 5.6.23 old-style gpl rpms(ex:rhel5) and observe /usr/my.cnf created by default
install el5 commercial repo config file
replace old-style rpms using mysql56-commercial repo using update or install command
observe /usr/my.cnf still exists though new style rpms use /etc/my.cnf config to start server by default

How to repeat:
yum -y remove 'mysql*' 'MySQL*'
rm -rf /var/lib/mysql /etc/my.cnf /usr/my.cnf
[lroot@viking77 Ramana]# yum -y localinstall 5.6.23/gpl/MySQL-*.rpm<--lets finish installation and observe database created this step itself

New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

[lroot@viking77 Ramana]# ls -lrt /usr/my.cnf 
-rw-r--r-- 1 root lroot 943 Feb 18 13:11 /usr/my.cnf

yum -y install mysql-commercial-release-el5-1.noarch.rpm
yum clean all
yum -y install 'mysql-commercial*'<--this will install 5.6-commercial packages

[lroot@viking77 Ramana]# ls /usr/my.cnf -lrt<--this still exists,which should have been removed
-rw-r--r-- 1 root lroot 943 Feb 18 13:11 /usr/my.cnf

Added the following text to:


 Installation of previous versions of MySQL using the older packages might
have created a configuration file named /usr/my.cnf.
It is highly recommended that you  examine the contents of the file and
migrate the desired settings inside to the
file /etc/my.cnf file, then remove /usr/my.cnf.
