When using our Download Monitor CSV Exporter/Importer extensions, upon importing the downloads to your new site you may notice that the IDs for the imported downloads do not correspond with the ones on your previous site.
Unfortunately, the Import plugin cannot create new downloads ( this goes for any custom post types ) with a specified ID as the ID is unique for each CPT on the whole site. It is not possible to have the same IDs that you had on the old website because those IDs are provided by the database and they are consecutive. For example if a new page is created and the ID 100 is assigned to by the database, we cannot use the same 100 as an ID for a download. Assigning the same ID as another post/page on the site will replace/remove it. Furthermore this is not allowed by WordPress.
