Creating new pages

I need this plugin to import menus from a staging site to the live site. My only concern is that this plugin creates pages. I have 96 pages and the XML export is 27000 lines of code containing all the page data. I only need the menu data and am concerned on what the page data will do to my live site content. I have some questions:

– If the pages already exist will an import create new/duplicate pages?

– If the pages already exist will an import overwrite any existing pages?

– Is there a way to switch off page creation? I see in a previous query to this you say ‘I advise you to make the corrections directly in the xml file generated by the export’, however in my case it will be far far quicker to manually recreate two complex menus than edit a 27000 lines of code.

Please advise. Thank you!
