Upgrading Cortex 3.0.1/ES5.6 to Cortex 3.1.0RC1/ES7.8
In my last post, I covered how I went about upgrading TheHive from 3.4 to 3.5RC1 along with a double upgrade of Elasticsearch. Well now its Cortex’s time. Cortex 3.1.0 also uses Elasticsearch 7.8 so we are in for a similar upgrade process. Depending on your reliance on Cortex it may be a nice addition to TheHive that is rarely used, or it may be critical to your operation. Either way, getting to the latest version is desirable as there are always welcome bug fixes and improvements with error handling, reporting and general integration.
