To Migrate Google Workspace to Office 365 for multiple users at once, the key is using a method that supports bulk migration—manual options won’t handle this efficiently.
A practical way is to use a tool like the SysInfo Google Workspace Backup Tool. Start by installing and opening the tool, then sign in using your admin credentials (via P12 or JSON file). Instead of selecting users one by one, you can import multiple user accounts using a CSV file. This lets you include all mailbox details in one go.
After that, select the Google Workspace services you want (like Gmail, Drive, Contacts, and Calendar). Choose Microsoft 365 as the destination, enter the required credentials, and apply any filters if needed (such as date range or skipping duplicates). Finally, click Start Migration.
