As part of a migration to Jive, some of the PDFs that came over didn't actually come over AS PDFs or come over with attachments. We aren't sure why, but we need to move forward regardless.
So after sourcing the old PDFs and investigating options, we have found that we can easily attach a PDF to the existing non-PDF content pieces -- BUT that doesn't change the content type (so if you filter by PDF, it doesn't show in the list).
Alternatively, we could simply start anew and post the PDFs the right way the first time, but that would then make someone other than the original author appear as the author.
Is there a way to manually change the content type?
