Updating Warranty Information in SCCM with Dell Client Integration Pack for MS System Center Configuration Manager 2012

I have installed the Warranty Information piece of the DCIP, and it works really well. My question is, now that I have run it once, what needs to be done to update the information?

In other words, can I just re-run the tool to gather warranty information from Dell without having to worry about duplicating information already in the database?

Thanks;
