Enterprise-Ready Migration Architecture

Built to support secure, compliant, and large-scale Google Workspace to Office 365 migration without compromising security or operational control

Large organisations migrating from Google Workspace to Microsoft 365 must meet stricter compliance, security, and data governance requirements throughout the migration process.

  • GDPR penalties reach 4% of turnover, increasing enterprise migration compliance risks.
  • Data residency regulations complicate cross-border enterprise migrations.
  • ICO requires breach notification within 72 hours of an incident being reported.
  • Domain-wide delegation required for bulk enterprise mailbox migration projects.
  • Google and Microsoft permission models differ, complicating access mapping.
  • Google API quota restrictions may slow data extraction & extend migration timelines for enterprise environments.
  • SOC 2, ISO 27001, and HIPAA frameworks require a documented audit trail.
  • Multi-tenant migrations demand precise user mapping across departments and domains.

Key Features of the Google Workspace to Microsoft 365 Migration Tool

Everything You Need to Migrate Google Workspace Data to Microsoft 365 Securely

Migrate

Migrate Gmail Mailbox to Exchange Online

The Aryson Google Workspace to Office 365 Migration Tool exports Gmail emails, attachments, labels, and folders directly into Exchange Online mailboxes using the Microsoft Graph API. It keeps the folder hierarchy, contacts, and calendar events completely intact. Also, it helps significantly reduce downtime by more than 70%.

Export Sharepoint

Migrate Google Drive to OneDrive/SharePoint

Google Drive migration mode transfers My Drive, Shared Drives, Shared with Me, and Trash data straight to OneDrive. Even a beginner can efficiently migrate files from Google Drive to SharePoint Online. Moreover, when users migrate from Google Workspace to Office 365, the folder hierarchy and metadata are kept intact without requiring third-party plug-ins or manual conversion at all.

Mapping

Batch Migrate Google Workspace Data

IT admins who manage large domains migrate 100+ accounts using batch CSV migration, uploading one file mapping source and destination users. Select all checkboxes to bulk-select every mailbox instantly, reducing the manual selection time and easing enterprise-scale Google Workspace to Office 365 rollouts, which significantly differ across departments.

Skip

Advanced Migration Filters for Precision Control

Toggle on the date range filters to target a specific migration window, or use advanced email filters to search the subject, to, from, CC, and BCC fields. Even the Drive's file type filter restricts migration to Docs, Sheets, Slides, or custom extensions, while min/max size filters exclude irrelevant files.

Date Range

Skip Duplicates & Skip Folders/Sections

The Skip Duplicates feature of the Aryson Google Workspace to Office 365 migration tool detects existing items via name, size, modification time, or checksum. Moreover, it prevents the transfer of redundant data when users migrate from Google Workspace to Office 365. Skip Folders and Skip Drive Sections exclude spam, trash, and "Shared with Me" content entirely, keeping only relevant enterprise data in the migration scope.

Saving Path

Attachment Handling & Folder Hierarchy

The Skip Attachments feature migrates emails without attachments for faster processing, while Save Attachments Separately stores them in a dedicated destination folder. Keep the folder hierarchy exactly the same as in the original Gmail label structure and Google Drive folder layout. This way, none of your essential data gets lost anywhere during the Office 365 migration.

Remove Duplicates

Custom Folder Naming & Output Organisation

You may assign a custom name to output folders and choose any destination path for saved results. Split Resultant File breaks large PST outputs into smaller parts by size, while Merged PDF Size Limit divides large exports into organised 500 MB parts for cleaner enterprise data management.

Split PST

Flexible User & Mailbox Mapping

While migrating to Microsoft 365, SharePoint Online, or another Google Workspace domain, the Google Workspace to M365 migration supports one-to-one, one-to-many, many-to-one, and many-to-many mapping types. Moreover, the Quick Actions automate bulk mapping with a selected source to all destinations or all sources to the selected destination. This eventually simplifies large-scale enterprise mailbox reassignment during any migration project.

remove-duplicate-item

Resume Migration & Server Space Management

Resume migration skips already-transferred items and continues an interrupted job without duplicating data, protecting business continuity during large migrations. Free Up Server Space lets admins move source items to the bin or delete them permanently after success. This optimises storage while maintaining full enterprise data governance control always.

Attachment

Secure, Local-Processing Architecture

The Aryson Google Workspace to Office 365 Migration Tool processes the entire data locally on the admin's own machine using OAuth 2.0 and the Microsoft Graph API. We never store credentials or Google Workspace data on external servers, keeping enterprise information fully under organizational control throughout every migration.

Hierarchy

Compliance-Ready Migration Trail

Every migration generates detailed logs and reports, giving IT teams the audit trail needed to support GDPR, SOC 2, ISO 27001, and HIPAA compliance requirements. Admins can demonstrate what data migrated, when, and where, satisfying enterprise and regulatory reporting obligations without extra tools.

Mailbox

Zero-Downtime & Business Continuity

Resume migration, date range filters, and batch processing let organizations pre-stage large Google Workspace to Office 365 migrations over time. Thus, it minimizes disruption to daily operations. Employees keep working while data transfers in the background, and IT teams control the final cutover window precisely.

Essential Migration Insights: Aryson Google Workspace to Office 365 Migration Tool

Find answers to the most common questions organizations ask before migrating from Google Workspace to Microsoft 365

Ans. Domain-Wide Delegation (DWD) lets a Google service account act on behalf of every user in your domain. It's needed because the tool cannot log into each mailbox one by one for a bulk migration. With DWD granted, it can read Gmail, Calendar, Contacts, and Drive data for all users at once.

Ans. The Google Workspace to M365 migration migrates data from both My Drive and Shared Drives while maintaining the original folder structure. During migration to Microsoft 365 OneDrive, My Drive content is transferred directly, whereas Shared Drives, Shared with Me, and Trash data are organized into dedicated folders within the destination OneDrive account.

Ans. To migrate data to Microsoft 365, the administrator account must be granted the required Microsoft Graph API permissions. These permissions include openId, profile, offline_access, User.Read.All, Directory.Read.All, Mail.ReadWrite, Contacts.ReadWrite, Calendars.ReadWrite, Tasks.ReadWrite.All, Files.ReadWrite.All, Sites.ReadWrite.All . These are mainly used to enable secure access and ensure successful migration of mailbox data, contacts, and calendars into the target Microsoft 365 environment.

Ans. On the Google side, the tool uses the Gmail API, Calendar API, People API, and Drive API. On the Microsoft side, it uses the Microsoft Graph API for mailbox, OneDrive, and SharePoint access. These APIs handle authentication, data reading, and data writing.

Ans. Yes, the Aryson Google to Microsoft 365 Migration tool provides a Save Credential option for all login methods. When enabled, account details are securely stored in a local SQLite database, allowing users to quickly access and re-authenticate saved accounts directly from the dashboard.

Ans. The trial version allows migration of up to 500 emails per folder, 100 calendar events, 100 contacts, 100 tasks, and 100 Google Keep notes. For Google Drive migration, it supports files up to 20 MB in size.

Ans. Yes, the software requires activation before use. It supports both online activation, which validates the license through a server, and offline activation, where an information file is generated for manual license verification.

Ans. Yes, when exporting to PST, the Google to Microsoft 365 Migration tool includes contacts, calendar events, and tasks along with emails. These items are saved in their respective folders within the PST file for easy access in Outlook.

Ans. If some Google Workspace mailboxes are missing after administrator login, it is usually due to insufficient permissions, incomplete API authorization, suspended user accounts, or the administrator account not having the necessary access rights to retrieve all mailbox data.

Ans. If the destination drive runs out of storage space, the tool automatically detects the issue and safely pauses the migration process. Once sufficient space is available, you can resume the operation without restarting it from the beginning.

Ans. Yes. The software supports batch migration using CSV-based account lists for multiple users at once. This is designed for organization-wide moves, not just single mailboxes. It saves time compared to migrating one account at a time.

Ans. The software allows you to back up data from multiple Google Drive sections, including My Drive, Shared with Me, Trash, and Shared Drives (Team Drives). This ensures comprehensive coverage of your Google Drive content.
