Backing up Ambari infra Solr data
In Ambari 7.1.x.x, Ambari Infra Solr uses Solr 8.4.1. For data stored in the existing Solr 5 implementation used by Ambari 2.6.2.x, the data stored in Ambari Infra must be backed up and the Ambari Infra Solr services must be upgraded.
The next section walks you through steps to both back up the data stored in Ambari Infra and upgrade the Ambari Infra components. The backed up data will be migrated and restored after the HDP upgrade is complete.
