Retain Subscription When Moving Reports to Different Workspaces

Subscriptions are tied to the report artifact in a specific workspace (and often the user + report ID). When you republish/recreate the report via ADO deployment, you’re effectively creating a new report object, so the old subscription objects don’t “follow” it. There isn’t a built-in way today to automatically retain them through redeployments.

If you want to avoid losing them, don’t replace the report in Prod. Instead keep the same report item and only update the dataset/model behind it.
