Imports also pages which I don’t want

I tried your plugin to transfer the menu structure from an old site to a new one. Reason was to link from the new site to the old site. The old menu had many and many of links. On the new site I have only a few necessary pages and want to link to the old page for the rest of the links.
When exporting and then importing I got all menues, but unfortunatelly it also imports the pages meta and destroys existing pages. Is it possible only import the menu structur (which has afterwards converted to URL links)?
