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.
