Yes, you can migrate from Google Workspace to Office 365 without significant downtime if you plan the process properly and use a reliable migration solution.

Instead of switching everything at once, many organizations migrate mailboxes in phases while users continue working in their Google Workspace accounts. Using a tool like the SysInfo G Suite to Office 365 Migration Tool, you can transfer emails, contacts, calendars, and Drive data directly in the background. Since the migration runs without affecting the original data, users can keep accessing their accounts during the process.

You can also migrate data in batches, apply date filters, and move only required mailboxes first. Once the data is successfully transferred, you can update domain settings and fully switch to Office 365. This approach helps minimize or even avoid downtime completely.
