I am unable to understand what the following sentence means and what action needs to be taken?
"*NOTE- Our raw Storage Devices data is out-of-date. ATUM 2.0 has updated Sub Towers. Upload the “Storage Tier
to Sub Tower” file and create a lookup using tier as the reference to the appropriate sub tower. Use the formula
below to populate your “IT Resource Sub Tower” column".
Please clarify where to upload and other steps.
