Raka, You will have to migrate it as part of a Workflow. Just incldue the New Notification Template on one of the Workflows and migrate it. The Notification Template should migrate along with WF as well. Thanks. -Raj
Actually, a notification template is used to initialize the definition of a notification. The notification starts out as a copy of the template and can then be customized for that specific notification. The resulting notification is migrated with the workflow but the notification template is not referenced by the workflow and is not migrated.
If you want to have the notification template defined in other instances, you will need to create it manually in each instance. This is done most easily by copying content from one and pasting it into the next.
