Hi We're quite early in the process of deciding what to do, and I'm aware that doing in place conversions is not optimal, we do have daily backups and if we do come up with something that can do these reconversions we'll probably work on a copy of the assetstore. I agree that having the documents converted to PDF/A before they are admitted is a better solution and that's something we're working on too.
For now the purpose is to get the national archive institution to accept our dspace as a valid archive, in short they'll want a copy of it and check it for compliance with their archival standards. Having the documents as PDF/A as I understand it is one of them.
