Elastic has introduced Automatic Migration, a feature designed to simplify the transition from existing SIEMs to Elastic Security by leveraging generative AI to map and translate detection rules, as outlined by Charles Davison and Mark Settle. This new capability, part of Elastic Security versions 8.18 and 9.0, aims to reduce the complexity and effort involved in migrating SIEM content by utilizing semantic search powered by the ELSER natural language processing model. Initially, Automatic Migration focuses on Splunk, with plans to support additional SIEMs and artifacts in the future. The feature uses AI to map existing detection rules to Elastic's prebuilt ones, translating unmatched rules into new Elastic queries and validating them for functionality. Elastic has tested Automatic Migration with real-world rulesets and offers it in technical preview to customers with specific licenses, enabling a faster, streamlined migration process.
