I’m looking for a way to upgrade all of my Google Cloud Functions to a new runtime in one go. Currently, I have multiple Cloud Functions running in different runtimes, and I want to streamline the process of upgrading them to a newer runtime version.

Current Setup:

• I have several Google Cloud Functions deployed in various runtimes, such as Node.js 12, Node.js 14, and Node.js 18.
• These functions are critical to my application and are deployed across different projects and regions within Google Cloud Platform (GCP).

Goal:

• Upgrade all existing Cloud Functions to a new runtime, such as Node.js 20 to leverage the latest features and optimizations.

My expectation is to migrate all your cloud functions to a new runtime at a single time, like a batch process.
