Serverless Migration Station is a Serverless Expeditions mini-series, designed to help developers modernize their applications to run on a Google Cloud serverless compute platform. In this third and final episode covering App Engine push queues, Google engineers Martin & Wesley refactor and rewrite a Python 2 Cloud NDB app already migrated to Cloud Tasks as a Python 3 app that uses Cloud Firestore. All three of these migrations are optional, so this represents a more realistic example involving more updated and added code than the samples featured in other episodes.
