This is not supported, you need to upgrade first to the last patch version of `7.17.X` and check the upgrade assistant if you need to change anything.

This is the **first thing** you see in the [documentation page](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html#setup-upgrade), please check the documentation.
