How do I change the runtime from Java EE 6 to Java EE 7 on SAP Cloud platform?

[#1]

Hi colleagues,

I have deployed a java servlet app on the SAP Cloud Platform on the EU demo account. The runtime used is Java EE6. We have changed the underlying architecture and would like to use the new runtime, Java EE7, and hence thinking about migrating the app from EE6 to EE7. But in the SAP Cloud platform cockpit, I couldn't change the runtime version without deleting the older app and then creating the new app. The problem is that I have utilized the PasswordStorage service in the SAP CP, and from the documentation, we see that the Entries would be deleted if the app is undeployed and then redeployed again. Is there any way to preserve the values of the PasswordStorage entries across undeploying - redeploying?

Or, is there any way to change the runtime directly without undeploying and redeploying the app?

Hello, Suhas. I would like give you a hint. Take a look at the screenshot below. I think you are able to update your APP JVM version in this popup. Find you APP and click Update button It allows you to modify some configurations of your App. thanks

Hi Zhao,

The problem Suhas has stated is not about the JVM Version but it is about the change of Runtime version?

Thanks and Regards, Ajay
