Yes, if an on demand router is managing the work sent to that static cluster.
Can the application edition manager support the deployment of one edition of an application to one cluster and the deployment of another edition to a different cluster?
Yes. The application edition manager supports different editions simultaneously deployed on different targets. You must establish routing policies for routing traffic to different editions.
Does the application edition manager support the activation of different editions on different members of the same cluster?
No.
Does the application edition manager restart the application or the entire server to activate a new edition?
No, the application edition manager does not restart the application or server. You must perform the following steps:

- Deactivate the active edition.
- Activate the new edition.
- Start the new edition.
Can the application edition manager handle the rollout of editions with incompatible changes?
Yes, the application edition manager can handle this situation if the on demand router is configured to perform edition-aware routing. See Edition compatibility.
