I have done an In-place upgrade on a test server but the home page still
retains the 2003 look & feel. I believe we had customized the home page
little bit in home page. All other pages (such as doc library, links etc)
have 2007 look & feel.

The customization to the home page are not important. I had read somewhere
that I should be able to 'throw away the customization' but I do not know
how to do that.

Any pointers to how can I throw away the customization and get MOSS 2007
look & feel (with Recycle bin & bread crumbs etc) for the home page.
