Changing a Lambda Runtime

I received the following notice from AWS

We are contacting you as we have identified that your AWS Account currently has one or more AWS Lambda functions using the Python 3.8 runtime.

Support for Python 3.8 on Lambda ends on October 14, 2024, so let's change the runtime version.

How to change the runtime

Open the Functions page in the Lambda console.

Select the function you want to update and choose the Code tab.

Scroll down to the Runtime settings section below the code editor and choose Edit.

Under Runtime, select the runtime identifier you want to use.

Click Save.

When "The function was updated successfully" appears in the header area, the change is complete.

Don't forget to verify that the target function still works correctly on the runtime you changed to.
