Is this ok [y/N]:y



Sucessfully installed.


# rpm -qa | grep TEST
TESTabc-3.1.0-04
TESTxyz-3.1.0-04


"yum install" is removing TESTabc-3.1.0-02, which I don't want. So, when
"yum install TESTabc-3.1.0-04"  is run successfully, I want to see old
version and new version of TESTabc and TESTxyz packages

# rpm -qa | grep TEST
TESTabc-3.1.0-02
TESTxyz-3.1.0-02
TESTabc-3.1.0-04
TESTxyz-3.1.0-04

So, is it a restriction on "yum install" that it will remove the old
version of the package once it successfully install new version of the
package.

Is there flag/way in yum, when I run "yum install TESTabc" I should see
both old and new version of TESTabc on the machine.


Thanks
Sunil.
