Hi Solr Team, We are planning to upgrade from Solr 3.5 to Solr 4.x version. Appreciate if you can provide any pointers/documentation on step by step by changes.
Also, the reason for upgrading is to use Solr join [not solr cloud or any other feature]. So which version is better Solr 4.0 or higher version considering the changes to be minimal during upgradation. Thanks, Subacini
