Google Workspace to Microsoft 365 migration
We migrate email and data from Google Workspace to Microsoft 365. We review compatibility for mailboxes, calendars, contacts and files to define the transfer scope and the preparation needed for the destination services, users and access arrangements before the change takes place.

Specialist services
We review email, files and the Google Workspace structure to design their destination in Microsoft 365. The plan covers functional differences, permissions, conversions and assistance during the change, taking account of both the information being moved and the way people will work with it afterwards.
What can be migrated
Migration scope from Google Workspace to Microsoft 365 depends on licences, data volumes, the Google Drive structure, use of shared drives, permissions and the tools selected for the process. These factors need review before the project so that supported transfers and any separate preparation or configuration work are identified clearly.
For email, we review Gmail, user mailboxes, labels, folders, contacts, calendars, rules and aliases. The usual destination is Exchange Online, accessed through Outlook, Outlook on the web and mobile applications, with the relevant accounts and mail flow prepared before users change platforms.
For documents, we analyse Google Drive, shared drives, folders, files, ownership, permissions, shared links and team structures. Depending on the requirements, data can be organised in OneDrive for individual users’ files, SharePoint for team spaces and Microsoft Teams for everyday collaboration, with each destination selected according to how the information should be accessed and managed.
Google Workspace and Microsoft 365
Migration changes how users access email, share files, collaborate on documents, manage meetings and work together. The project therefore needs to consider the working practices associated with the destination services, alongside the transfer of information. Users need to understand where their data will be and how to access it after the change.
When moving from Gmail to Outlook and Exchange Online, users begin working with Microsoft 365 mailboxes, Outlook calendars, rules, shared mailboxes and centralised administration of business email. When moving from Google Drive to OneDrive, SharePoint and Teams, it is important to decide which information is personal, which belongs to teams and which document libraries should be created to keep it organised. This helps establish a destination structure suited to the organisation’s requirements rather than simply reproducing folders without considering how the platforms differ.
We also review the effect on permissions, shared links, mobile devices, installed applications, file synchronisation, authentication, DNS, mail flow, groups and internal communication. Migration needs to address both the transfer of data and the preparation of the new way of working, with the required configuration, instructions and validation included in the plan.
Key considerations
One of the most important considerations is the email. Users need to be prepared in Microsoft 365, domains reviewed, DNS records validated, the MX change planned and sending and receiving checked after the transition. These activities must be coordinated with the mailbox transfer so that the destination service is ready for users at the agreed change point.
Another critical area is files and permissions. Google Drive may contain personal files, shared drives, different owners, public links, inherited permissions and unclear structures. Before moving this information to OneDrive or SharePoint, it is important to review what should be retained, what can be archived and which permissions are appropriate for the destination. These decisions affect both transfer and subsequent access.
It is also important to consider user adoption. Employees will move from Gmail to Outlook, Google Drive to OneDrive or SharePoint, and Google Meet or Chat to Teams, with a different collaboration model. Communication, usage guidance and subsequent support therefore matter alongside the technical work, helping people understand how to use the services prepared for them in Microsoft 365.
The migration process
Implementation is organised into the following phases. The activities, dependencies and checks for each stage are defined within the scope agreed for the project and the environment involved.
Before and after migration
Before starting, the organisation should decide which data must migrate, which accounts remain active, which users will participate in the pilot, how OneDrive and SharePoint will be structured, how Microsoft Teams teams will be organised and which permissions should be retained or recreated. These decisions establish both the transfer scope and the configuration needed in the destination.
Internal communication also needs preparation. Users should know when the change will happen, when to stop using Gmail, when to start using Outlook, how they will access files, what will happen to calendars and contacts and whom to contact with questions. The instructions should reflect the sequence agreed for their services and user group.
After migration, the environment needs to be operational and validated. We check sending and receiving, calendars, contacts, migrated files, permissions, OneDrive access, SharePoint libraries, Teams usage, device synchronisation and Microsoft 365 application settings. These checks assess the result against the information and services included in the agreed scope and identify any remaining work required after the transition.
Service follow-up
We agree the scope, responsibilities and priorities with your team. We document the work and the checks carried out. Any additional requirement is assessed before it is incorporated into the project or the support service, so that the implications for the agreed work are understood.
Frequently asked questions
We answer common questions about moving from G Suite or Google Workspace to Microsoft 365. We also include links to official documentation for further technical detail, helping clarify the transfer methods, destination services and preparation needed before the migration approach is selected and the change is scheduled.
Yes. G Suite was the previous name of Google’s business suite. Its current official name is Google Workspace, although many businesses still search for the service using the G Suite name when considering administration, support or migration.
Google explains on its official website that Google Workspace is the evolution of G Suite and includes tools such as Gmail, Calendar, Meet, Chat, Drive, Docs, Sheets, Slides, Forms and Sites. See the official page for Google Workspace.
Migration can be planned for Gmail email, contacts, calendars, Google Drive, shared drives, documents and collaborative data into Microsoft 365 services such as Exchange Online, OneDrive, SharePoint and Teams. The scope depends on the source structure, supported features and tools available for each workload, which need to be reviewed before committing to transfer.
Microsoft documents migration of email, calendars and contacts from Google Workspace to Microsoft 365 in its official guide to Google Workspace migration to Microsoft 365.
Yes. We can migrate Gmail to Exchange Online so that users work with Outlook, Outlook on the web and Microsoft 365 mobile applications. The project prepares the destination mailboxes and access arrangements and establishes how mail flow will change when users begin working in the new environment.
Before migration, we review mailboxes, users, domains, calendars, contacts, aliases, rules, mail flow and DNS to reduce problems during the transition and define the checks needed afterwards.
Yes. Many scenarios support migration of calendars and contacts from Google Workspace to Microsoft 365. The exact scope depends on the source configuration, accounts, tools used and compatibility of the process. We assess those requirements before the project so that the items to be transferred and their validation are defined clearly.
Microsoft’s Google Workspace migration documentation identifies features such as email, rules, calendars and contacts that can be migrated into Microsoft 365, subject to the requirements and limitations of the method used.
Yes. We can plan file migration from Google Drive to OneDrive, SharePoint or Teams according to whether the information is personal, departmental or collaborative. The destination structure and permissions should reflect the way the data needs to be used, shared and administered in the Microsoft 365 environment.
Microsoft provides official documentation on migrating Google files to Microsoft 365 with Migration Manager and on migrating Google Workspace to Microsoft 365 with Migration Manager.
Shared drives need a specific review because ownership, permissions, shared files, external links and collaboration structures may differ from those in OneDrive or SharePoint. The transfer method and destination should be selected with those differences in mind, rather than assuming that the source access model can be reproduced unchanged.
Before migration, we assess whether each shared drive should become a SharePoint library, a Teams team or another document structure within Microsoft 365, based on the information and collaboration requirements involved.
It depends on the destination platform, source structure and tools used. Permissions can be retained or mapped in some cases; in others, rebuilding them is a better way to improve security and avoid carrying over an unclear structure. We review the access requirements before defining how permissions should be transferred or recreated.
Before moving files, we review users, groups, owners, shared links, external access and inherited permissions to define a consistent strategy for Microsoft 365 and the services that will hold the information.
We plan the migration to reduce interruptions. Much of the destination can usually be prepared before the final change, but the transition from Gmail to Exchange Online and the DNS record changes require a controlled window. The sequence needs to coordinate the transfer of data, mail flow and user access to the new environment.
Before carrying out the transition, we define dates, affected users, internal communication, validation activities and the support plan, so that responsibilities and the required actions are understood in advance.
Timing depends on user count, mailbox sizes, the volume of Google Drive files, number of shared drives, permissions, synchronisation speed and environment complexity. These factors need to be assessed together before estimating preparation, transfer, cutover and the validation needed to confirm that the services work in the destination.
After the initial assessment, we can estimate the work by phase. For medium or large environments, we recommend a pilot, migration in batches and validation before the wider change to Microsoft 365.
After the change, users may need to sign in to Microsoft 365, configure Outlook, review calendars and contacts, access OneDrive or SharePoint, install Teams and check that their main files are available. The exact steps depend on the services moved, device configuration and the destination access arrangements prepared for them.
We can assist users with initial support, basic instructions and incident resolution to make the transition easier and help them begin working with the services and information available in the new environment.
Yes. After migration, we can help with validation, incidents, Outlook configuration, OneDrive, SharePoint, Teams, permissions, documentation and administration recommendations. The follow-up work is defined around the services moved and the support requirements agreed with the organisation for the period after the transition has been completed.
We can also provide basic user training and guidance on good working practices in Microsoft 365, according to the requirements and scope agreed with the organisation for subsequent support.
