**Tell us about your request**
A command to change the owner (created by) of a service, that's means user or role

**Which service(s) is this request for?**
Fargate

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
A user activates his account to support the new ARN format and create cluster/services, after that leaves the company and the account is deleted.

Is not possible increase/decrease the task running in that service using another account (also with support to new ARN) , because you get the error message:

_error Task long arn format must be enabled for launching service tasks with ECS managed tags._

**Are you currently working around this issue?**
The only way to do it is:

1. not erase that account who create the service, or
2. activate the support for longARN to root account, or
3. re-build the cluster and service with another user/role

**Additional context**
N/A

**Attachments**

No repository files, tests, or entry points are named. Start by reviewing the ECS/Fargate service ownership behavior and the reported long-ARN error; the requested outcome is a supported way to change the user or role that created a service so another account can scale its tasks.
