Hi @John Doe
A few solutions are offered in a similar topic:
Solution 1) Migrate using SharePoint Designer
Solution 2) ShareGate (https://sharegate.com/)
Edit: Removed Mover from solution list.

I would try reaching out to ShareGate for their solution at https://sharegate.com/features/plan-analyze-monitor-migration (they are offering tenant to tenant solutions).
Hi @John Doe ,
I am looking forward to your feedback if there is any update.
Please remember to update this thread if you have any progress.
Thank you for your understanding.
