Here you can select which page templates included in the import package will be imported. The following extra option can be adjusted:
•Import all site specific page template scopes - if checked, site-specific page template scopes will be imported for all page templates, even if a page template itself is not selected to be imported. This check-box is only displayed with page templates in the Global section of the tree and only when the import package contains an exported website, not only separate objects. If you are importing to an existing site, this option is de-selected by default.
•Import web part and zone variants with the selected page templates - if checked, web part and zone variants (from MVT testing) included in the package will be imported together with the selected page templates.
Detailed information about the built-in export/import functionality in Kentico CMS can be found in Developer's Guide -> Managing sites -> Export and import.
