I didn't even know that downgrade was possible, but it would seem it only works for certain packages, not the whole system. From the man page:

Code:

downgrade
              Will try and downgrade a  package  from  the  version  currently
              installed  to  the  previously highest version (or the specified
              version).  The depsolver will not necessarily work, but  if  you
              specify  all the packages it should work (and thus. all the sim-
              ple cases will work). Also this does not work for  "installonly"
              packages,  like  Kernels.  downgrade  operates on groups, files,
              provides, filelists and rpm files just like the  "install"  com-
              mand.

Spin up another guest, install 6.4, install packages as required.

KISS.

First, read the LQ Rules, "Question Guidelines", and "How to ask a smart question" links in my posting signature. This is NOT URGENT FOR ANYONE HERE...we are volunteers. Asking for/expecting 'urgent' help is fairly rude.

Since this was 'urgent'...did you try putting "how to downgrade centos 6.7 to 6.4" into Google?? The VERY FIRST HIT:
https://access.redhat.com/solutions/186763

...are instructions. This is for RHEL, but CentOS is 99.x% IDENTICAL, and this will probably work. Bear in mind that unless you UPgraded that server from 6.4 to 6.7, then a downgrade is NOT POSSIBLE.

Downgrade the WHOLE OS to a UNSUPPORTED VERSION ?????

WHY ???

now downgrading ONE or a few programs in 6.7
that is doable

i have a old box with a gforce2 card and have to downgrade Xorg to 1.13 ( the version in 6.3 )

it is a pain in the rear but it is doable

so

WHY!!! do you NEED!!!! to use a unsupported Operating System ?
