NCOA Utility

I'm looking for organizations, particularly consortia, that use or have used the NCOA Utility for address updates/corrections.

We want to explore this but have heard that the utility overwrites the address without leaving an inactive copy of the old address, which contradicts our data audit trail process.

Has anyone used the utility? Has anyone customized the utility to fine-tune it for their organization's needs?

Thanks!
