+# SAP Cloud SDK for JavaScript Version 4 Upgrade Guide <!-- omit from toc -->
+
+The purpose of this document is to collect information on the Cloud SDK version 3 to version 4 migration.
+It should include information on all steps a user needs to take when updating the SDK version from 3 to 4.
+
+This document should be written in a style which addresses the consumer of the SDK.
+It will eventually end up in the SDK docs portal and release notes for version 4.
+
+Please add your items below when creating a change which will involve manual tasks for the user when performing the upgrade.
+Add sections to the document as you see fit.
+
+<!-- Everything below this line should be written in the style of end user documentation. If you need to add hints for SDK developers, to that above. -->

+# How to Upgrade to Version 4 of the SAP Cloud SDK for JavaScript <!-- omit from toc -->
+
+This document will guide you through the steps necessary to upgrade to version 4 of the SAP Cloud SDK.
+Depending on your project, some steps might not be applicable. The To-Do list is:
+
+- [Update Your Project Dependencies](#update-your-project-dependencies)
+- [Update to Node 22 or Newer](#update-to-node-22-or-newer)
+
+## Update Your Project Dependencies
+
+Search for occurrences of `@sap-cloud-sdk/[some module]` in your `package.json` files.
+Replace the version numbers with `^4`.
+Depending on if you're using `npm` or `yarn`, run `npm install` or `yarn` in the directories of your `package.json` files to update the `package-lock.json` or `yarn.lock` file.
+
+Running your tests or deploying your application might fail at this point in time if you need to adapt to any breaking changes.
+We recommend updating your applications in one commit or pull request and making sure everything still works using your existing test suite.
+
+## Update to Node 22 or Newer
+
+All SAP Cloud SDK for JavaScript libraries now support node 22 (LTS) as the **minimum** node version.
+If you are using a node version older than 22, update your runtime environment to a newer version.
+On Cloud Foundry you can do this by [setting the node engine in your `package.json`](https://docs.cloudfoundry.org/buildpacks/node/index.html#runtime).
