Box to OneDrive Migration

Frequently Asked Questions

Frequently Asked Questions for Box to OneDrive


  • Question: What gets transferred?

Answer: Only owned folders and the root files for each user are copied. If a user isn't the owner of data they can access, we don't copy it. Content may be automatically re-shared after it's migrated so that each user has access to their content exactly as before.


  • Question: What happens to Box Notes?

Answer: Box Notes will not be converted during migration to a .docx format. If you have Box notes, please copy the contents out and create them as a OneNote or a Word document.

  • Question: Can I rearrange content during a migration?

Answer: Not recommended. Any major changes in directory structure should happen before or after your migration. It's also not a good idea to use our app to rearrange content. The risks that come with rearranging content during the migration are primarily in the form of data duplication; our incremental process sees all changes as new data. So, for example, if you change a folder name at the root, we detect that as a new folder, and all of the contents is retransferred, including all subfolders. When sharing permissions are transferred, both owners and collaborators receive duplicate data if content has been rearranged or renamed.


  • Question: Does the Migration delete my files?

Answer: No. We never delete your data from any source. We take your data from one place and copy it to another; akin to copy and paste rather than cut and paste. We also don't retain any of your cloud storage data for any reasons.


  • Question: What happens to external sharing links?

Answer: We don't recreate external sharing links. After migration, these have to be set in the destination manually.


  • Question: Does the Migration sync files?

Answer: There's a source-to-destination delta; when we run a transfer, we compare the destination directory to the source, and only transfer new or modified files over. We call this our incremental feature. We compare the timestamps of the files in both the source and destination and transfer the newest versions only. The incremental feature is always on. Here are a few examples of how we deal with changes to files and folders.

· Content changes: If a document is edited in your source or you've added a few new files, we copy them to your destination on the next incremental run, overwriting the previously existing file(s) in the destination.

· Name changes: If the name of a file or folder changes, we treat it as a brand new object. This can lead to duplicate files being migrated to OneDrive, or worse in that entire folders worth of data would be duplicated from the changed folder downwards.

· Example: Changing the path /Sales/Clients to /Global Sales/Clients results in two copies of your Sales folder after the Global Sales folder is also copied during an incremental pass.


  • Question: Files and Folders that are owned by BoxAdmin

Files and folders owned by BoxAdmin will be addressed separately. We will be analyzing them and breaking them into appropriate departments. We are still in the process of deciding how best to move forward with this process.


  • Question: What if I already have folders in OneDrive?

If you have folders in OneDrive that have the same name, it’s possible that those documents could be duplicated. Review the “Does the Migration sync files” section.


  • Question: What if I have PII or HIPPA files?

The migration does not store any content on the migration servers. Files and folders names are stored in a database to facilitate the incremental copies. These servers are located in our Azure datacenter and controlled by our staff.
