It doesn’t make any sense that the importer doesn’t work with the built in exporter. I’ve attempted to export the data as an xml file and import it into the native WordPress importer, but that just gives me this error:
Sorry, there has been an error.
This does not appear to be a WXR file, missing/invalid WXR version number
I’m taking the data from the export file and reformatting it to match the sample csv file. My worry with this system is that the links appear to use a post id for downloads ex. /?wpdmdl=13025. The importer doesn’t seem to have a way for me to assign an identifier, it just gives me an ID column if I would like to update an existing post. In my case my new website has other post types that already occupy some of these IDs. Is there a way to migrate these files/data and keep the /?wpdmdl=someid links in my content working under these circumstances?
