轻松完成从App Engine上的Python 2.5到2.7的迁移

Question

I have some "old" GAE Python 2.5 applications, with a lot of code. This year we have to (goolge says) migrate to Python 2.7. I never touched the software for the last two years. The apps run fine without any administration. Some applications still use the Master/Slave datastore, which will be migrated first.

This software uses webapp and Jinja and no other external libraries besides SDK 1.7.2 (2012).

The scenario: Keep webapp / CGI (do not change the code) and only change this yaml:

application: example
version: 1
runtime: python
api_version: 1

To:

application: example
version: 2
runtime: python27
api_version: 1
threadsafe: false

And testing the applications with the new Python 2.7.

Is this the minimal effort scenario for migrating 2.5 applications to 2.7?

是的，这是您的最低要求，但是您应该阅读Migrate到Python 2.7文档，并确保覆盖了所有要点。
