There is a way to ask: rpm -q

Actually, what I would do, would be probably something like this:

cd download-dir
for i in `rpm -qa` ; do mv $i* ../upgrade-dir ; done
cd ../upgrade-dir
rpm -Uvh *

Possible problems:
rpm -qa is perhaps to long for the shell.
rpms sometime replace rpms with different names.
