 Many legacy App Engine first generation platform (Python 2, Java 8, PHP 5, and Go 1.11 & older) services are available ([as of Sep 2021](https://twitter.com/googledevs/status/1445916786755571712) for second generation runtimes (Python 3, Java 11/17, PHP 7/8, and Go 1.12 & newer) in a public preview. There are no videos or codelabs yet, however the Module 1 Flask migration using App Engine `ndb` [Python 2 sample](/mod1-flask) is available in [Python 3](/mod1b-flask) if you have access. Similarly, Python 3 editions are also available for Modules 7 and 12 which add usage of App Engine `taskqueue` and `memcache`, respectively. Also see the [documentation on accessing bundled services from Python 3](https://cloud.google.com/appengine/docs/standard/python3/services/access).

 # Module 19 - Migrate from App Engine `taskqueue` (pull tasks) to Cloud Pub/Sub (and Python 3)
 
-This repo folder is the corresponding Python 2 code to the [Module 19 codelab](http://g.co/codelabs/pae-migrate-pubsub). The tutorial STARTs with the Python 2 code in the [Module 18 repo folder](/mod18-gaepull) and leads developers through its migration from pull tasks via App Engine `taskqueue` to Cloud Pub/Sub and Python 3, culminating in the code in this folder. The migration from App Engine `ndb` to Cloud NDB, covered in Module 2, also takes place.

-**NOTE:** While this solution Python 2 compatible, a library conflict on App Engine servers does not allow it to run properly under Python 2 on App Engine.)

The code is both Python 2 and 3 compatible, and either uncomment the Python 3 runtime in `app.yaml` and delete all other lines, or just use `app3.yaml`, delete `appengine_config.py` and any `lib` folder.
