### Questions about destinations
Q: What plugins do I need installed besides Alerting?
A: To continue using the notification action in the Alerting plugin, you need to install the backend plugins `notifications-core` and `notifications`. You can also install the Notifications Dashboards plugin to manage Notification channels via OpenSearch Dasboards.
Q: Can I still create destinations?
A: No, destinations have been deprecated and can no longer be created/edited.
Q: Will I need to move my destinations to the Notifications plugin?
A: No. To upgrade users, a background process will automatically move destinations to notification channels. These channels will have the same ID as the destinations, and monitor execution will choose the correct ID, so you don't have to make any changes to the monitor's definition. The migrated destinations will be deleted.
Q: What happens if any destinations fail to migrate?
A: If a destination failed to migrate, the monitor will continue using it until the monitor is migrated to a notification channel. You don't need to do anything in this case.
Q: Do I need to install the Notifications plugins if monitors can still use destinations?
A: Yes. The fallback on destination is to prevent failures in sending messages if migration fails; however, the Notification plugin is what actually sends the message. Not having the Notification plugin installed will lead to the action failing.
