+# Migrate to v3
+
+!!! warning
+    UI5 Tooling v3 is currently in development. Further breaking changes are expected.  
+    The latest development version can be installed via `npm i -D @ui5/cli@next`
+
+## Breaking changes
+
+**All UI5 Tooling Modules Require Node.js >= 16.13.2 / npm >= 8**
+
+Support for older Node.js and npm releases has been dropped.
+Only Node.js v16.13.2 and npm v8 or higher are supported.
+
+**Removal of tasks and processors**
+
+The following tasks have been removed:
+
+- createDebugFiles
+- uglify
+
+The following processors have been removed:
+
+- debugFileCreator
+- resourceCopier
+- uglifier
+
+As a replacement, the new 'minify' task and 'minifier' processor can be
+used.
+
+Note: The minify task is executed earlier, before the bundling
+process takes place. Any existing 'beforeTask' or 'afterTask' configuration of
+custom tasks might need to be adapted to cater for this change.
+
+Updated list of standard tasks:
