Hi Martin,
You can update only carridgeMin and cartridgeMax at runtime in application
update. Even you can update the deployment policy which uses the
application. But you cannot change the deployment policy in application at
runtime.
In your case, as you have used two different deployment policies, it won't
work. It will use the previous deployment policy. I have tested following
scenario.
1. Use the deployment policy with partition max as 1.
2. Deploy the application with cartridgeMin 1.
3. Update the same deployment policy with partition max 2.
4. Update application at runtime to cartridgeMin 2.
4. Another instance spawned successfully.
Thank you!
