Backing up Ambari infra data and migrating Atlas data
In Ambari 7.1.x.x, Ambari Infra Solr uses Solr 7. 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. In the HDP intermediate bits, Atlas data must be migrated from one graph implementation to another. This requires backing up the Atlas graph data before the HDP intermediate bits upgrade, so that it can be automatically migrated during the HDP intermediate bits upgrade process. The next sections outline the steps required to backup and configure Atlas for this migration process.
