First download rpms.  Next rebuild them.  Move all of the rebuilt stuff into /data/done-local5/staging-signing.

Sign above rpms.  su to distrib on polo or rabbit, copy relevant rpms from /data/done-local5/staging-signing to /data/done-local5/staging
then run from tools dir
{{{
./do-merge-staging-updates-PU_IAS-5.sh
}}}
to see what will happen. If all looks good then run
{{{
./do-merge-staging-updates-PU_IAS-5.sh -a -r
}}}
which will apply changes (-a) and remove (-r) all rpms that it filed away and only leave the ones it doesn't know what to do about.
