AWS Lambda Node运行时从Node.js v4.3更新到Node.js v8.10

Question

We created a function in AWS Lambda using Node v4.3 . Later we upgraded the function to Node v8.10 . When I just update the runtime of the function, it updates the runtime fine and I can execute the code just fine without errors.

It that all needed to upgrade from Node.js v4.3 to Node.js v8.10 ?

I used the following command:

aws lambda update-function-configuration --function-name functionname --runtime nodejs8.10

Is this a clean way to perform an upgrade of the runtime version of Node.js in Lambda or am I missing something?

Answer 1

Yes, normally that is all that is needed. The key is testing to ensure nothing breaks. You can also verify via the GUI that the function is using the new runtime.
