We have a DSpace instance which we are trying to migrate using the AIP
packager but are running into an error with duplicate bitstream ids.
The stack trace:
Exception: Error exporting METS for DSpace Object, type=ITEM,
handle=10642/1095, dbID=1152
org.dspace.content.packager.PackageValidationException: Error exporting

I'm confused by the bitstream_-1 value as checking this record in the
database shows me that all bitstreams are stored correctly. I did read
elsewhere that there was an issue with sequence numbers; could this be the
issue? And if so, is there a way to resolve this problem by directly
modifying the database?
Any suggestions greatly appreciated.
Thanks
Hayden
