OneDrive and Google Drive move with the mailbox migration when files are in scope. Files stream through MigrateX in chunks — never written to disk — and sharing is re-granted to the matched people in the target.
What moves
- Every file and folder in the personal drive, with created and modified dates.
- Sharing: each person a file is shared with is looked up in the user mapping and re-granted the same role in the target. Sharing links and external people are listed as notes instead — nothing is guessed.
- Google Docs, Sheets and Slides are exported as Word, Excel and PowerPoint when leaving Google. Office files stay as they are.
- Google Drive to Google Drive copies inside Google (share → copy → unshare), so it is fast and the file never leaves Google.
A target user without a OneDrive
A Microsoft 365 user who has never opened OneDrive does not have one yet. MigrateX asks Microsoft to create it and waits — the row shows Creating the OneDrive for a few minutes, then the copy starts by itself. The user needs a license that includes OneDrive and must be allowed to sign in; if not, the row says so by name.
What doesn't
- Version history — the current version moves.
- OneNote notebooks and other packages — listed by name for manual follow-up.
- Files changed since they were copied are picked up by the next delta pass; verification also flags them.
