## Version Compatibility with Elasticsearch

Ideally, you should be running Elasticsearch and Kibana with matching version numbers. If your Elasticsearch has an older version number or a newer _major_ number than Kibana, then Kibana will fail to run. If Elasticsearch has a newer minor or patch number than Kibana, then the Kibana Server will log a warning.

_Note: The version numbers below are only examples, meant to illustrate the relationships between different types of version numbers._

| Situation                 | Example Kibana version     | Example ES version | Outcome |
| ------------------------- | -------------------------- |------------------- | ------- |
| Versions are the same.    | 7.15.1                     | 7.15.1             | 💚 OK      |
| ES patch number is newer. | 7.15.__0__                 | 7.15.__1__         | ⚠️ Logged warning      |
| ES minor number is newer. | 7.__14__.2                 | 7.__15__.0         | ⚠️ Logged warning      |
| ES major number is newer. | __7__.15.1                 | __8__.0.0          | 🚫 Fatal error      |
| ES patch number is older. | 7.15.__1__                 | 7.15.__0__         | ⚠️ Logged warning      |
| ES minor number is older. | 7.__15__.1                 | 7.__14__.2         | 🚫 Fatal error      |
| ES major number is older. | __8__.0.0                  | __7__.15.1         | 🚫 Fatal error      |
