I have an old website with several GBs of media data. i want to export the media files with wordpress export / import tool to my new website. Wordpress gives me a 10mb .xml file out of the several GBs media data. I understand that WordPress Import/Export feature does not physically move the media files themselves. it creates some sort of mapping.
my concern is that the media files remain hosted on the old site and are accessed from there, even though they appear to be on the new site. so if i deleted the old side i lose all the media data.
I just need some clarifications please.
