Google Workspace to microsoft 365 migration
When we are migrating from Google workspace to Microsoft 365 using Microsoft automated migration method, what are the chances of emails getting duplicated if in Google an email has multiple labels tagged.
And also, what's the limit of user data we can migrate per day and how many concurrent users we can migrate?

We completed a Google Workspace to Microsoft 365 migration recently, and the key was spending enough time on planning before the actual cutover. Make sure all Microsoft 365 user accounts are created, verify your domains, and perform a pilot migration with a few users first. That helps identify any permission or configuration issues early.
If you're migrating more than just email, it's worth using a migration tool that can handle mailbox data, contacts, calendars, and other supported items while preserving the folder structure. We had a good experience using the EdbMails Google Workspace Migration Tool because it supports direct Google Workspace to Microsoft 365 migration, allows incremental synchronization, and lets you migrate in batches to minimize downtime.
After the migration, don't forget to validate mailbox contents, update DNS records (MX, SPF, DKIM, and DMARC if applicable), and keep the source environment available for a short period until users confirm everything has been migrated successfully.
Regardless of the tool you choose, testing with a small group before migrating everyone is one of the best ways to ensure a smooth transition.
One thing to be aware of is that Gmail uses labels rather than traditional folders, while Microsoft 365 uses folders. During migration, multiple Gmail labels can sometimes result in the same email appearing in multiple folders, depending on how the migration tool handles label mapping. It's worth checking the documentation of the migration method you're using and running a pilot migration with a few test mailboxes first.
Regarding migration limits, the actual throughput depends on factors such as Microsoft 365 throttling policies, network bandwidth, mailbox sizes, and the migration method. There isn't a single fixed daily data limit that applies to every environment, and the number of concurrent users also depends on the migration solution and available resources.
If you're evaluating alternatives, you can also look at the EdbMails Google Workspace Migration Tool. It supports direct Google Workspace to Microsoft 365 migration and includes incremental migration, which is useful for synchronizing any new emails that arrive after the initial migration. Regardless of the tool you choose, I'd recommend starting with a pilot migration to validate label-to-folder mapping, permissions, and overall migration performance before migrating all users.
Good questions, these come up often with Google Workspace migrations.
Email duplication and labels
Google labels do not create duplicate emails in Microsoft 365. During automated migration, each message is migrated once. Labels are converted to folders where possible, but the email itself is not duplicated even if it had multiple labels in Gmail.
Migration limits
Microsoft does not publish a strict per day data cap for Google Workspace migrations. In practice, limits depend on tenant throttling, mailbox size, and network conditions. For small and mid size tenants, migrating all users concurrently is common and supported. Large mailboxes simply take longer.

- When migrating from Google Workspace to Microsoft 365, there's a chance of duplicated emails if they have multiple labels because each label might create a copy during the transfer. As for the limits, it typically depends on the method you’re using and your plan. You can usually migrate up to 500 MB of data per user per day, but check Microsoft's guidelines for specifics on concurrent user limits.
During the manual migration process, emails that have multiple labels in Google Workspace can lead to duplication in Microsoft 365. Outlook treats each label in Gmail as a separate folder, causing this issue. But using tools like https://www.drssoftech.com/google-workspace-to-microsoft-365-migration/, which can eliminate all duplicate emails during the migration process, your output data is more precise. Apart from this, you can also migrate bulk Google Workspace data into Microsoft 365 with just a few clicks. As a tech expert, I recommend trying this tool and migrating data with minimal downtime.
The decision to switch from Google Workspace to Office 365 was driven by our need for enhanced collaboration features and better integration with Microsoft products. After researching various tools, I opted for the MigrateEmails G Suite to Office 365 Migration tool, which promised a seamless transition. The interface of the migration tool was user-friendly, making it easy for someone without extensive technical knowledge to navigate through the process. The setup involved creating a Google Service Account and configuring the necessary permissions, which was straightforward thanks to the detailed instructions provided within the tool.
