Dear Dale, I've never used the DSpace Solr import/export scripts. I always had some issues with them somehow. A few years ago I discovered this excellent https://github.com/freedev/solr-import-export-json utility and I do all Solr work using that, including migrating from DSpace 6 to DSpace 7 earlier this year.
First, export from DSpace 6 Solr (adjust output file as needed, depending on size of stats): $ ./run.sh -s http://localhost:8081/solr/statistics -a export -o /tmp/statistics.json -k uid Then import into DSpace 7: $ ./run.sh -s http://localhost:8983/solr/statistics -a import -o /tmp/statistics.json -k uid You can even do things like limit the export to a certain range, for example 2023: $ ./run.sh -s http://localhost:8081/solr/statistics -a export -o /tmp/statistics-2023.json -f 'time:[2023-01-01T00\:00\:00Z TO 2023-12-31T23\:59\:59Z]' -k uid This is useful if you want to migrate stats up to a certain date before moving to DSpace 7, then import the remaining ones after moving the production server, for example. Hope that gives you another solution, Regards On Wed, Nov 27, 2024 at 1:37 PM 'Poulter, Dale' via DSpace Technical Support <dspace-tech@googlegroups.com> wrote: > Good morning, > > > > We are trying to import older statistics to Dspace 7.6 but are getting a > null pointer exeception when skipping dns lookup.
