Hello, Pen_224
Welcome to Microsoft Community.
If you're transferring files between two different OneDrive accounts, there are a couple of ways to approach it. I'll give you the most straightforward methods:
1.Download the Files: Log into your first OneDrive account -<onedrive.live.com> and download the files you want to transfer to your computer. You can:
•Select individual files or folders and click Download.
•Or, create a ZIP archive if you're dealing with multiple files.
2.Switch Accounts: Log out of the first OneDrive account and log into the second account.
3.Upload the Files:
•Navigate to the folder where you want to place the downloaded files.
•Click Upload, then select the files or ZIP archive to upload them.
Additional tips: If your files are larger than 250GB or if you are uploading, downloading or moving a large number of files at once, you may have to wait longer for the process to complete.
>> However, this also depends on whether your internet service operator has set a speed limit on the upload bandwidth of your home/personal network. For more details on these limits, please refer to:Restrictions and limitations in OneDrive and SharePoint - Microsoft Support
In addition, if your account was previously a student account authorised for use by the university, consider using Mover to assist you with this migration process. Please refer to this article: Transfer files to your personal OneDrive with the Mover Transfer Wizard - Microsoft Support
