Hello Raja Karmakar
Microsoft Whiteboards created with a Family or personal account are stored separately from Whiteboards created with a Business account. Personal boards are accessed through the Whiteboard board picker, while business boards are stored as .whiteboard files in OneDrive for Business. Because of this, there is currently no direct self-service option to migrate the editable boards between these accounts
As a workaround, open each board using the personal account and use Settings >Export image to save a copy. You can then upload or insert the exported content into a new board under the Business account, although the imported copy may not retain the original editable objects.
Thank you for your understanding
