How do I upgrade a Prod Server to Match a Test Server using Subscription Manger or just yum/rpm Rhel 6.6

Latest response

I a Prod and Test server. both running Rhel 6.6 but Test has newer installed packages and Kernel then Prod.
I need to get Prod to match Test. I have tried the following but when I try to downloadonly, yum will try to install
newer packages even know I have the rhel version set to 6.6

Here is how I try to create a localinstall, Is there a better way ?

On Test Server
rpm -qa --last > list
vi list # remove old installs from list,
cat list | cut -d " " -f1 > list1 # removes date from every line
vi list1 #added this under vi editor # 1,$s/^/echo y | yum upgrade --downloadonly --downloaddir=\/home\/userone\/packages /g

Then on Prod Server.
mkdir /home/userone/packages
./list1
yum localupdate *.rpm

Here is where I yum will install newer packages.... Please Help.
