Clearing Build Statistics for a Project

Hi,

I think I saw this posted before, but I could not find it.  

We are deploying a TeamCity 6.5 server.  In bringing the server up, there are many failed and invalid build.  Is it possible to reset all the parameters and history of the build to be blank (basically, starting fresh)?

I was thinking of copying "project-config.xml" and then going to "Administration->ProjectName" and hitting "Delete", then creating a new project and copying the project-config.xml back.  Is there a better method?

Thanks,
John
