After migrating documents to SharePoint as PDFs with attachments, the PDFs are then moved to a NAS drive (Network folder). The attachments folder in SharePoint is also moved to NAS but when when the PDFs are opened, the attachments don't work as there is SharePoint dependecy for the URLs. Is there a way to change this so that migrated PDF and attachments will open when moved to another location without having any SP dependencies?
Unfortunately with already migrated documents into SharePoint there is nothing that can be done to resolve this issue.
If you re-migrate from Notes, you can put all attachments into the PDF as self contained attachments or you can migrate your documents to PDF/A.
