I have been looking into moving a large collection of files from OneDrive to Google Drive, mainly because I want to bring work documents and personal files into one storage environment. The difficult part is not simply moving the files; I also want the existing folder structure to remain organized after the transfer. Recreating folders manually for hundreds of documents would take a lot of time and could easily result in misplaced files.

One thing I found useful is the ability to apply filters before starting the migration. For example, if I only need documents, PDFs, presentations, or specific file types, I can select those extensions instead of moving everything. Date-based filtering is also helpful when the migration only needs to include recently modified data. This makes the process more controlled and avoids transferring unnecessary files.

Another concern is whether file details will remain available after migration. Being able to preview file names, types, sizes, and creation or modification dates before starting gives better visibility into what is actually being moved. For a large collection, this kind of checking can make the migration easier to manage.

For my situation, I am considering using a solution that can migrate OneDrive data directly to Google Drive rather than downloading everything first and uploading it again. The option to migrate OneDrive to Google Drive seems particularly useful when dealing with multiple folders and a large number of files.

I also came across the SysInfo OneDrive Migration Tool while comparing different approaches. What caught my attention was its support for selective migration, multiple date ranges, file-extension filtering, and folder hierarchy preservation. The ability to stop or resume the migration is another practical feature when the transfer cannot be completed in a single session.

I am still deciding which approach makes the most sense for a larger migration. Has anyone here handled a similar project and found a reliable way to transfer files from OneDrive to Google Drive while keeping the folder organization intact?
