In a migration to Microsoft 365, your email, calendars, files and devices move to Microsoft's cloud: Exchange Online, SharePoint, OneDrive and Teams, with Intune for managing laptops and phones. Suradj Bajaj guides that move from inventory to aftercare, so your team can simply keep working. Ahoy Rotterdam (200 devices) and Bird Group (Intune and SharePoint), among others, have gone before you.
Mailboxes, calendars and contacts moved to Exchange Online, from your own Exchange server or another email environment.
The file server moved to SharePoint Online for shared folders and OneDrive for personal files, with the right permissions per team.
Windows devices managed through Microsoft Intune: existing devices via Microsoft Entra hybrid join, or with a clean Windows 11 installation.
Conditional Access policies and identity & access management, so only the right people on the right devices can reach company data.
A migration runs in six steps. That way you know in advance what happens, when, and what it asks of your team.
Users, mailboxes, files, devices, licences and integrations with other software are mapped out.
You get a concrete plan with the sequence, timeline and risks, aligned with the busy periods in your organisation.
Licences, domain verification and security settings, plus a pilot group that tests the new environment first.
Email and files are moved over, in phases per department where possible, so day-to-day work carries on.
Devices are enrolled in Intune and the Conditional Access policies go live.
Your staff are shown the new setup, and I stay involved after the switch to resolve questions and teething problems.
A switch for a small team is different from a migration of hundreds of workstations. After the inventory you get a tailor-made schedule. These are the factors that set the pace:

Read the caseIn April 2020 Microsoft renamed its Office 365 plans for small and medium-sized businesses to Microsoft 365. Office 365 revolves around the Office apps and online services such as Exchange, SharePoint, OneDrive and Teams. Microsoft 365 plans such as Business Premium add device management with Intune and extra security.
Yes, that is the starting point. The switch is planned so that staff notice as little of it as possible: the final cutover happens at a quiet moment and a pilot group catches problems in advance. At Ahoy Rotterdam the migration went ahead without disrupting daily operations.
Shared folders move to SharePoint Online and personal files to OneDrive. After that, the file server can be phased out. That is also how it went at Ahoy Rotterdam, where all files on the file server were moved to SharePoint Online.
Not necessarily. Existing Windows devices can be brought under management via Microsoft Entra hybrid join (formerly Hybrid Azure AD Join) and Intune, as at Ahoy Rotterdam. Sometimes a clean start is better: at Bryte, all workstations got a fresh Windows 11 installation.
That depends on the number of users, the amount of data and your current environment. After a no-obligation introduction and a short inventory, you receive a tailor-made proposal. On top of that, you pay for Microsoft 365 licences per user per month.
Plan a no-obligation call. We will discuss your current environment and you will get honest advice on the approach and the timeline.
