Dear dspace-tech,

We're in the middle of an upgrade from DSpace 5.8 to DSpace 6.3. After processing our Solr stats with the as-of-yet unreleased Dspace 6.4 SolrUpgradePre6xStatistics class we have a large number of Solr statistics records with "-unmigrated" IDs. In my tests with only a small fraction of our ten-year Solr history we have 300,000 unmigrated records, which leads me to believe we'd have millions if I attempted to process our entire Solr history.

I see that the records with "unmigrated" IDs have correct UUIDs for their owningComm and owningColl fields, so all that's missing would be for them to have a unique UUID for their ID. Why do these fail to migrate? Could I generate UUIDs for them manually? What do other people do with these records?

Thanks,
