Any way to clear inventory?

I'm using the included Sybase Inventory with ZCM 11.1. We are also using Service Desk. In the next few weeks, we will be upgrading to the most recent version of Service Desk, and as such, we will need to re-import the inventory from Zenworks.

We want to clear out our inventory database and start again as we have changed some of the things that we want Zenworks Inventory to track. Is there a way to do this?

Thanks
