What is the correct way to transfer ownership so as not to incur unnecessary charges?

Hello, I have a question about the fees that are incurred during file ownership transfers.

● Question
I tested transferring ownership of files from a “free account” to a “paid account”, but the “paid account” has a new monthly charge.
However, I do not want to make any more mistakes in testing again,
Can you please tell me the correct official “how to transfer ownership without incurring extra charges”?

● Accounts I use, 2 types in total
A, a free account for personal use.
B, paid account for company use. (professional plan, annual subscription already paid)

● Operation performed this time

  1. Create a test file for the free account.
  2. Send the file to a paid account for sharing with “read-only” permissions.
  3. Accept file invitations with a paid account.
  4. On the free account, change the paid account’s permissions to “Owner”.
  5. The free account automatically switches to “Editor” by the operation in #4 above.
  6. On the free account, move the above file to “Draft”.
  7. On the paid account, move the received file to the “Team Project with Pro Plan Paid”.
  8. Over

I suspect that perhaps i moved the file to a “paid team project” while the account that became the editor remained in place, thus incurring a new charge.
