/api/v2/task_lists/{id}/move

Moves a task list — and all of its tasks — to a different folder, optionally in a different project. Provide the target folder_id.

When the target project uses a different workflow than the source, a map of workflow status IDs is required: keys are the source workflow's status IDs, values are the target workflow's status IDs. The map must cover every status in the source workflow.

Tasks are reassigned to the target project and their statuses remapped accordingly. Assignees and subscribers who are not members of the target project are removed from the moved tasks.
