 ### openHAB 3 / openHAB 4  to openHAB 4.3 or Later - Migration
 
 From openHAB 4 onwards, the script engine is GraalJS provided by the [JS Scripting Addon](https://www.openhab.org/addons/automation/jsscripting/), **ECMAScript 2022**, when Blockly creates new scripts.
-OpenHAB versions before 4.3 could use **ECMAScript 2022** or **NashornJS** with **ECMAScript 5.1**, either installed by default or installed through an Addon.
+openHAB versions before 4.3 could use **ECMAScript 2022** or **NashornJS** with **ECMAScript 5.1**, either installed by default or installed through an Addon.
 **NashornJS** is no longer an option with openHAB 4.3 or later. Therefore the generated Blockly code needs to be converted to **ECMAScript 2022**.
 
 Converting is as easy as making sure the [JS Scripting Addon](https://www.openhab.org/addons/automation/jsscripting/) is installed, and opening your Blockly script.

 You will need to provide a working Java installation on your DiskStation.
 The sections below are written for Java 11 but the docs are not updated currently, since we have not secured knowledge about how to install Java 17 on the DiskStation.
 If you can provide some proper sources and explanation, we are happy to include your contribution into this article.
