Our business has been using Dropbox BUSINESS Standard as a file storage solution for the last 6 years.
We are now transitioning to G Suite Business.
In Dropbox, there are 39 users, 5 groups, and 7 Team Folders.
Mission : move all data from Dropbox to Google Drive + maintain folders and files permissions.
(Team Folders in Dropbox > Shared drives in Google Drive)
NOTE : Retaining the group and users permission access level/rights across is a challenge that needs to be addressed in your response.
I would like to emphasis on the fact we are a business, and all the files we have been storing for 6 Years and precious and important data for us. We can't afford loosing any of this, and we are after someone professional
