Classic to Claims migration of SP 2010 web application

Hi,

I want to migrate the web application of classic authentication in SharePoint 2010 to a new web application based on claims authentication in sharepoint 2010. i.e. both the web applications in the same farm (single server).

Can someone guide me on how to proceed with this?

I just created a new web application with Claims authentication. And stucked how to migrate the content db of classis web app to claims web app. And what needs to be done next.

Thanks, Krishna
