Google Workspace Adoption & Migration
Google Workspace Adoption & Migration: move with confidence
We introduce Google Workspace in your company and move your email, calendars, files and collaboration – whether you're coming from Microsoft 365, HCL Notes, Dropbox, Box or your own mail server. With a pilot, a coexistence phase and a clear timeline.
- A migration plan with a pilot and waves instead of a big bang
- From Microsoft 365, HCL Notes, Dropbox, Box, file servers or IMAP mail servers
- Licenses directly from us as an official Google Cloud Partner and official Google Workspace and Google Cloud Reseller
Starting point
From wherever you work today to Google Workspace
Microsoft 365 and Exchange
The most common path: Exchange, OneDrive, SharePoint and Teams content. You'll find everything about it below.
HCL Notes and Domino
Email, calendars and contacts move with Google's own migration tool. We replace Notes applications as part of legacy modernization.
Dropbox and Box
Files and folders move to Google Drive – with shared drives and a clean permissions concept.
Your own mail or file server
We move IMAP mailboxes, PST archives and Windows file shares into Gmail and Drive in an orderly way.
Zoom, Slack and others
Meetings and chats move to Google Meet and Google Chat. For chat histories, we use specialized migration tools where needed.
New rollout without a legacy system
For new companies and growing teams: set up your domain, accounts, security and folder structure properly from day one.
Focus: Microsoft 365
Switching from Microsoft 365 to Google Workspace
Microsoft 365 has become more expensive – a good moment to review your platform
Microsoft raised the list prices for Microsoft 365 as of July 1, 2026 (according to Microsoft); existing contracts are affected from their first renewal after that date. Our Google Workspace cost calculator works out what a switch means for your company, using current prices from both providers.

What replaces what?
Microsoft 365Exchange Online
Gmail and Google Calendar
Mailboxes, calendars, contacts and shared mailboxes move over. During the coexistence phase, both worlds can see each other's free/busy times.
Microsoft 365SharePoint and OneDrive
Google Drive and Sites
Personal files go to “My Drive”, team and project data to shared drives with clear permissions. We rebuild intranet pages with Google Sites.
Microsoft 365Teams
Google Meet and Google Chat
Meetings, chats and spaces for teams. External guests join via a link, without an account of their own.
Microsoft 365Word, Excel, PowerPoint
Docs, Sheets, Slides
Real-time co-editing. Office files can still be opened and edited in Drive wherever the format matters.
Microsoft 365Copilot
Gemini
Gemini in Gmail and the Gemini app is included from Business Starter, in Docs, Sheets, Meet and Drive from Business Standard – without an additional license.
Approach
How the rollout works
A migration rarely fails because of the technology – it fails because of missing planning and users who don't know where their files are on day one. That's why we start with an inventory and a pilot, then move in waves – with a coexistence phase in which email and calendars work between the old and the new environment.
01
Inventory
Capture mailboxes, data volumes, folder structures, permissions, devices and dependencies in your current system. Result: target picture, wave plan and risks.
02
Target architecture
Define domains, identities (e.g. Entra ID or another identity provider), shared drives, permissions concept and security policies.
03
Pilot
A representative group works productively in Google Workspace. Lessons learned feed into templates, training and the wave plan.
04
Migration in waves
Move email, calendars, contacts and files department by department, with coexistence during the transition and the mail delivery cutover at the planned time.
05
Adoption and operations
Role-based training, contacts in each business unit, then operations and further development as Managed Google Workspace.
Intune, Entra ID and Windows can stay
Switching to Google Workspace doesn't mean replacing your entire Microsoft environment. Many companies keep Entra ID as their central sign-in and continue to manage their Windows devices with Intune. Google Workspace is then connected via single sign-on, and users and groups are provisioned automatically from Entra ID. Office desktop apps stay where individual teams really need them. As an affiliate of the Groß Group, we also have deep Microsoft expertise in-house.

We also support the move to Microsoft 365
Not every path leads to Google Workspace. If you're moving from Google Workspace to Microsoft 365 – for example after an acquisition or because of a group policy – you get the same care from us: inventory, pilot and migration in waves. For this, we work with the Microsoft specialists of our Groß Group. And if you run both worlds side by side for the long term, you get a clean coexistence.

Frequently asked questions
Most often from Microsoft 365 and Exchange. We also migrate from HCL Notes, IMAP mail servers, PST archives, Dropbox, Box and Windows file shares. For Slack chat histories, we use specialized tools where needed.
Yes. Together with the Microsoft specialists of our Groß Group, we also support migrations from Google Workspace to Microsoft 365 – with the same method of inventory, pilot and migration in waves.
For companies that want email, calendars and collaboration from a single source, Gmail with Google Calendar in Google Workspace is the obvious alternative. Mailboxes, calendars and contacts can be transferred; during the transition, Exchange and Google users can see each other's free/busy times.
Team and project data moves to shared drives in Google Drive, and intranet pages are rebuilt with Google Sites. A permissions concept up front is key: who may see and edit which shared drive? We use the opportunity to tidy up grown SharePoint structures instead of copying them one to one.
That depends on the number of users, the data volume and your coexistence needs. A few weeks for inventory and pilot are typical, followed by the cutover in waves. In the initial consultation, we give you a realistic assessment for your environment.
We plan the switch around the end of your contract so you avoid paying for both platforms at once. During the transition, both systems run in parallel in a controlled way.
Yes. Entra ID can remain the identity provider for Google Workspace – with single sign-on and automatic user provisioning – and Windows devices can still be managed with Intune.
Yes. Gemini is included from Business Starter, in Gmail and the Gemini app; in Docs, Sheets, Meet and Drive from Business Standard – without an additional license.
