Upgrading from Vista 34bit to Windows 7 64 bit and want to upgrade Photo/Premier from 10 to 13. What do I do first, next and last to not loose existing cataloges and DVD projects?

I have bought a New Computer w/Windows 7 and want to update Adobe Premiere/{Photoshop from 10 Vista to 13 Windows 7.  What do I do first?  Do I update on old computer under Vista or new computer under Windows 7? Also, I do not want complications accessing completed projects made in Vista or rebuild catalogs in Photoshop.
