 ### How to migrate runtimes?
 
-There are no constraints when changing a function runtime, you simply need to choose the runtime version you want.
-Upgrading a runtime is highly recommended in case of deprecation, and for runtimes that have reached end-of-support or end-of-life. See the [functions runtimes lifecycle documentation](/serverless-functions/reference-content/functions-runtimes/) for more information.
+On a Serverless Function, you can change the runtime if it's from the same family. Example: migrate from `go1.23` to `go1.24` To change programming language, create a new Serverless Function.
