Renaming a published task in a public extension

Given a public Azure DevOps extension, is there a way to change the task name (while keeping the id), that would maintain compatibility with pipelines that are referencing that task by its previous name?

The task.json schema does not mention support for aliases.

Solution

It's not able to directly rename a public published task.

We could be able to unpublish a task and re-publish item

To unpublish, select the extension on your publisher page and choose Unpublish on the menu. Your extension is unpublished immediately from the Marketplace, and new users can't install it. Ratings and reviews for your extension stays intact.
To offer your extension again in the Marketplace, choose Publish on the menu.

But not confirm if it will effect maintain compatibility with pipelines that are referencing that task by its previous name.

For this area, suggest you directly send questions about publishing items to the Visual Studio Marketplace to vsmarketplace@microsoft.com.
