There is a yum plugin to do this ... it is called yum-downloadonly, so

yum install yum-downloadonly

Afterwards do this to see how to use the pluging:

yum --help

Basically ...

yum --downloadonly upgrade

This will put all the updates into the /var/cache/yum/

(This will be all the updates for the packagelist on the current machine
... so if you want to get them all, make sure to duplicate the machine
packagelist you want to get the downloads for)

you can then copy these files to the new machine(s) /var/cache/yum/

Thanks,
Johnny Hughes
