I have had the exact same experience with trying to copy my online advanced subscription to another online advanced subscription. The new company subscription window is greyed out disallowing the transfer of the data files. I’ve spoken with 6 different tech support agents and spent over 5 frustrating hours trying to get someone to help me to no avail!!! My husband and I own a CPA firm, all of our employees are CPA certified Quickbooks Account Pros, we have numerous subscriptions ourselves and clients with subscriptions and spend a LOT of money each month with Intuit. At this point I am completely disappointed in their product and lack of qualified tech support agents to help. What do we do now????
