I have an existing 3.x installation that is in desperate need of an upgrade. However, an in-place upgrade is not doable, and stakeholders want to see what 6.0 would look and feel like before ok'ing the upgrade. So I've performed a clean install of DSpace 6.0 on a new VM and have started migrating data and customizing the interface. I've managed to move the database over, and it migrated just fine. After reindexing, I am able to find all the expected records. I have not yet migrated over the assetstore, so I can't confirm yet that I can access the digital objects themselves.
However, I have tried to migrate another section of necessary data and have run into issues: statistics. I tried to fake an upgrade by copying over the production [dspace]/solr/statistics folder. The ant upgrade task noted the out of date solr indexes and said it successfully migrated them. However when I tried to run [dspace]/bin/dspace solr-reindex-statistics, I received the following error: Exception: SolrCore 'statistics' is not available due to init failure: Error Instantiating Update Handler, solr.DirectUpdateHandler2 failed to instantiate org.apache.solr.update.UpdateHandler org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: SolrCore 'statistics' is not available due to init failure: Error Instantiating Update Handler, solr.DirectUpdateHandler2 failed to instantiate org.apache.solr.update.UpdateHandler at org.apache.solr.client.solrj.impl.HttpSolrServer.executeMethod(HttpSolrServer.java:552) at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:210) at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:206) at org.apache.solr.client.solrj.request.CoreAdminRequest.process(CoreAdminRequest.java:510) at org.dspace.util.SolrImportExport.reindex(SolrImportExport.java:320) at org.dspace.util.SolrImportExport.main(SolrImportExport.java:184) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.dspace.app.launcher.ScriptLauncher.runOneCommand(ScriptLauncher.java:229) at org.dspace.app.launcher.ScriptLauncher.main(ScriptLauncher.java:81) 3.x is old enough that [dspace]/bin/dspace solr-export-statistics does not exist. Any other suggestions on how to move my stats data over to the new server? Loss of stats data is a big deal to the stakeholders.
