Hi All,
Currently, We are in process of upgrading existing Solr indexes from Solr 4.x to Solr 6.2.1. In order to upgrade existing indexes we are planning to use IndexUpgrader class in sequential manner from Solr 4.x to Solr 5.x and Solr 5.x to Solr 6.2.1. While preforming the upgrdation a strange behaviour is noticed where all the previous segments are getting merged to one single large segment. We need to preserve the original segments as single large segment is getting bulkier (~ 2-4 TBs). Please let me know how to tune the process or write custom logic to overcome it. Thanks, Manan Sheth ________________________________ NOTE: This message may contain information that is confidential, proprietary, privileged or otherwise protected by law.
