Today I was trying to export one of my site from one Virtual machine to another. First I took a export of the web from my source server and then I tried to import the content in the destination server. And then the import failed with the error “The exported site is based on the template STS#1 but the destination site is based on the template STS#0”. I couldn’t remember the template with which I created the source site but I took for granted from the error message that the source and destination web are not created from the same template. After googling I finally found import will only work if source and destination web are created from the same template. In my case the source site was created from Blank Site template (STS#1) but the destination site was created from Team site template (STS#0).
So I deleted the destination site and recreated with the source template and the import was successful. For full lists of web site templates you can followAravindhan’s posts.
