    [Note]Note

    If you delete a tier, you will lose all its annotations.

    If you delete a parent tier, all its child tiers will be automatically deleted as well. Please make sure that you do not accidentally delete a child tier.

To delete a parent tier without deleting its child tiers, you have to assign the child tier to another parent or make it an independent tier. Afterwards you can safely remove the parent tier. For instructions on how to change a tier’s parent, see Section 5.4.7.
