Importing moss 2007 website to SharePoint 2010 using sites.asmx

Hello,

I have exported a moss 2007 site using sites.asmx which has created .cmp files in a document library of that site. I have to import that site to SharePoint 2010, for which I have created a web application and a blank site collection in SharePoint 2010. But when I am using ImportWeb method of sites.asmx then the result is coming as 5 (ImportFileNoAccess).

I need to know if it is possible or not. If yes then how can I import moss 2007 site to SharePoint 2010.

Regards, Shruti
