ODM OneDrive migration failed with: This site has exceeded its maximum file storage limit.
Each Microsoft license has its own OneDrive storage space limit set per user and when this limit is reached, the migration will fail with "This site has exceeded its maximum file storage limit." message.
Assign Microsoft license with higher OneDrive storage limit, or remove files and folders which should not be migrated to ensure you are within the storage limit in target and run the migration again.
