I need to transfer 300 TB worth of data (video files) from one Dropbox account to another, what would be the best way of doing it reasonably quickly?
Thanks in advance!
There's a help center article "Move files between two Dropbox accounts" here that should be helpful for information on doing this manually.
To use the same sharing functionality via the API, e.g., to automate this, you can use the sharing endpoints. Also, check out our developer Sharing Guide (specifically, the "Shared Folders" section).
