I have a large amount of data that I am holding in my Dropbox account (1.2TB) for legal purposes as advised by my attorney. The purpose is to show that the files have not been altered and being hosted by a third party is critical to that objective. The third party is Dropbox. But, I need more space and want to use a Family Plan but I can't get that. Is it possible for me to setup another drop box account, share the directory containing these files with that account and disconnect it from my current account and then change my current account to a Family Plan with the explicit intent of the date and time stamps of these files being what they are today?
