Here is a Microsoft Power Automate template, "Copy files from one OneDrive account or folder to another", maybe it could help you.
(Please note, the flow only works for transferring files, not folders.)
Otherwise, you need to download all the files that you want to transfer and synchronize them with your new OneDrive account.
Any questions, please let us know.
