This PR is in preparation for the ES 9 release. Lucene has BWC with indices created on one version prior to the current version (ES 9.0 is Lucene 10, so can support Lucene 9). To ensure that a system index created on an ES 7 (Lucene 8) can actually run on ES 9 (Lucene 10), the system indices need to be reindexed.
To reindex a system index for ES 9, the cluster need to be ugraded to
8.latestand then run the Kibana Upgrade Assistant or use the Feature MIgration APIs directly. The feature migration APIs enable you to see what features require changes, initiate the automatic migration process, and check migration status.For system indices to show up as "needs upgrade" in the
GET /_migration/system_featuresthe minimum index and stack version need to be bumped from 7 to 8. The suffix added to migrated indices also need to use version 9.
