That's actually what the upgrade procedure ought to do, because sharding was not included when working out the separation of Solr from the DSpace build (which was required by changes in the packaging of currently supported Solr versions). There may be a way to make it work, but the tools that currently come with DSpace will not help. Sharding is awaiting some discussion: o Does sharding actually help? o Consider that we are abusing a feature which was meant for evenly spreading load across multiple hosts. o This could be done much more simply and organically, without involving DSpace code at all, using Time Routed Aliases, but TRA requires Solr Cloud, which runs a bit differently. Is the benefit of sharding (whatever that actually is) worth the trouble to set up a (possibly degenerate) Cloud? -- Mark H.
