How do Match Prod to Test Server Rhel revisions level, Yum or other

Latest response

Yum/Classic, how to I get a Prod server to match rhel OS versions installed on a TEST server to match.

Matching installed Rhel product versions from Prod to a Test server that is newer by 6 months,
both are 6.7 and the same kernel 2.6.32-573.12.1.el6.x86_64

Not sure how to do using the Classic or by using Yum
