Here you can select which widgets included in the import package will be imported. When importing from a previous version of Kentico CMS, a warning is displayed, so that you are careful not to overwrite current physical files with the ones from the previous version.

 

Detailed information about the built-in export/import functionality in Kentico CMS can be found in Developer's Guide -> Managing sites -> Export and import.
