App Engine switch to High Replication

Question

Am I right in thinking you CANNOT change a Goole AppEngine Application into High Replication.

What you do is migrate to a new app that is High Replication. Delete the App re create as High Replication and migrate back.

Is there a quicker way?

Answer 1

Migrating Applications (official guide from Google)

but basically:

1. You cannot change.
2. Clone the application.
3. Migrate the Data.
4. Disable old app.
