**ElasticSearch update requires index rebuild, potentially more filespace**
While it is generally possible to keep ElasticSearch indices in an upgrade (see [Configuring the Elasticsearch storage path](/setup/install-server/)), this version's upgrade of ElasticSearch will force all indices to be rebuilt. Additionally, more filespace may be required for this version's data ([SONAR-11826](https://jira.sonarsource.com/browse/SONAR-11826)).
