Move G Drive with mover

I was looking to contact with on of mover support team to understand a couple of points of mover service. Now we are using G suite product, we do have many separated accounts in G suite but we would like to move to Microsoft Business 365 (one account for the whole company with different domains). As I understood from Microsoft documentation that migrating to Microsoft Business will pull emails, calendar and other items but not including folders/files in G drive and this is where mover comes to bring on the table.

My question as follows
We are facing an issue with our G Drive as we are using G Drive as a document management system. We have root folders owned by individual then sub-folders owned by another individual but it’s shared across. Kindly find below example where each point represent a folder name and (name) between (braces) represents the owner of the folder/file

1- Current projects (Yasser)
a. Project A (Yasser)
b. Project B (Eric)
i. Planning (Eric)

1. File 1.xlsx
2. File 2.exe
   ii. Designing (David)
   iii. Execution (Yasser)

c. Project C (David)
i. Proposal.ppt (Yasser)
2- Archive (Eric)
a. Project D (David)
i. Deliverables (Yasser)

1. Expense details.xlsx (Eric)
2. Final Presentation (Yasser)
   ii. Notes.txt
   b. Project E (Eric)

Some files size is exceeding 10 GB and definitely, others are below 10 GB. Ownership of each folder/file is distributed among the team.
My question, how can we migrate all of these folders without losing the data nether hierarchy or sorting of the folders? (tree). This is becoming a nightmare for us to accomplish
We are talking about around 300 GB for 150 users in total and could be more.

Appreciate helping us out and advise moving forward

Best regards,
