Subscribing Peter´s opinion, you should never loss the original
For the controversy, I rather move the original PDF to another bundle and the converted PDF/A would left at the ORIGINAL Bundle

And add the needed metadata to document the change, at least add some lines into a new dc.description.provenance (I know, there are better solutions, but this is simpler). They would serve as a pseudo preservation-metadata-record

Thanks

I wouldn't recommend altering/damaging your existing PDF's. That just sounds like its inviting risk.

A better route would be to build a DSpace curation task, that is capable of doing the automated PDF conversion, leaving the old PDF's in the ORIGINAL bundle, and the PDF/A's going into a bundle such as CONVERTED.

Also, what conversion tools are you looking at? i.e. a Java library / remote web service? Also, I'd take a look at the license, hopefully a compatible license with DSpace (i.e. non GPL, non AGPL).
