Moving from traditional Active Directory or Hybrid Microsoft Entra Join to Microsoft Entra Join isn't simply a matter of changing how a Windows device is joined.
The change can affect device management, authentication, applications, certificates, Group Policy, user profiles, and access to on-premises resources.
For IT teams planning the transition, the more useful question is therefore not just:
"How do we join these devices to Entra ID?"
It's:
"How do we move them while keeping users productive and devices manageable?"
Here's a practical way to think about it.
What changes with Microsoft Entra Join?
A Microsoft Entra joined Windows device is joined directly to the organization's Microsoft Entra ID tenant.
Users authenticate using their organizational account, while services such as Microsoft Intune can handle application deployment, configuration, compliance, and other device-management functions.
This differs from Hybrid Microsoft Entra Join.
With Hybrid Join, the Windows device remains joined to the on-premises Active Directory domain while also having an identity in Microsoft Entra ID.
With Entra Join, the endpoint itself no longer depends on AD domain membership.
That distinction becomes particularly important for organizations trying to reduce their dependency on traditional on-premises infrastructure.
Why organizations move toward Entra Join
There isn't one universal reason, but several benefits tend to drive these projects.
1. Better support for distributed devices
Traditional domain-joined environments were designed around reliable connectivity to corporate infrastructure.
That's increasingly awkward when devices are spread across homes, branch offices, and multiple countries.
Entra Join combined with cloud-based management can reduce the amount of device administration that depends on a device being physically connected to the corporate network.
2. Cloud-based device management
With Intune, administrators can centrally deploy applications, configure settings, evaluate compliance, and manage supported Windows devices.
This also creates an opportunity to reconsider old configurations rather than blindly reproducing years of accumulated Group Policy.
3. Modern authentication and access controls
Entra joined devices can participate in a broader identity-based security model using technologies such as:
- Microsoft Entra Conditional Access
- Microsoft Intune compliance
- Multifactor authentication
- Windows Hello for Business
It's important, however, not to treat Entra Join itself as a security control that automatically enables all of these protections.
The actual security posture depends on how the surrounding services and policies are configured.
Before migrating, identify your dependencies
This is one of the most important parts of the project.
Before changing device identity, determine what still relies on the existing AD environment.
Check areas such as:
- Group Policy
- AD computer authentication
- certificates
- Wi-Fi authentication
- VPN
- printers
- file shares
- line-of-business applications
- scripts
- device-based access rules
- existing Intune enrollment
- Conditional Access
Moving the Windows endpoint to Entra Join does not automatically eliminate every Active Directory dependency.
Some applications or resources may continue to require connectivity to the corporate network or domain controllers.
Then decide how the devices should move
There are several possible approaches, and the correct one depends heavily on the state of the device fleet.
Option 1: Windows Autopilot
Autopilot makes sense when you're:
- deploying new hardware,
- refreshing existing devices,
- or intentionally rebuilding devices onto a clean configuration.
For an existing AD or Hybrid joined device, a reset/rebuild followed by Autopilot provisioning provides a clean path toward an Entra joined and Intune-managed state.
The trade-off is continuity.
Applications, settings, and user data have to be accounted for as part of the reprovisioning process.
Option 2: Manual migration
For a small number of machines, an administrator can manually remove a device from its existing domain and join it to Microsoft Entra ID.
This can avoid a complete Windows wipe.
However, there's an important catch:
Changing the join state doesn't automatically map the old AD user profile to the new Entra user identity.
Profile handling, permissions, Intune enrollment, applications, and post-migration validation still have to be addressed.
For a handful of machines, that may be manageable.
For hundreds or thousands, it quickly becomes an operational challenge.
Option 3: In-place migration
Another approach is to migrate suitable existing Windows devices in place.
The goal here is different from a rebuild:
change the device identity while preserving as much of the existing working environment as possible.
This can be useful when wiping hundreds or thousands of otherwise healthy devices would introduce unnecessary user disruption.
However, "no wipe" shouldn't be interpreted as "nothing changes."
Depending on the environment, users may still need to:
- sign in again,
- recreate Windows Hello credentials,
- reauthenticate to certain applications,
- receive replacement certificates,
- restart the device,
- or complete application-specific validation.
That's why a representative pilot is essential.
Don't start with the entire fleet
Regardless of the migration method, avoid treating the first deployment as a mass rollout.
Start with a representative pilot.
Include devices that reflect the real environment:
- remote users
- office users
- different hardware models
- different business units
- critical applications
- VPN-dependent users
- users with legacy dependencies
Then measure what happens.
Look at:
- migration duration
- application behavior
- authentication
- Intune enrollment
- compliance
- Conditional Access
- user-profile behavior
- certificates
- access to on-premises resources
- support incidents
Only after those results are understood should the migration expand into larger waves.
One migration method doesn't have to fit every device
This is often overlooked.
An organization might use:
Autopilot for new and rebuilt devices.
Manual migration for a handful of exceptions.
In-place migration for healthy existing devices where preserving the working environment is important.
That's often more practical than forcing the entire fleet through a single workflow.
The migration architecture should follow the condition of the fleet and the desired outcome—not the other way around.
What about preserving the existing Windows profile?
This is where specialized migration tooling can become relevant.
For example, Opsole Migrate is designed for supported Windows device identity migrations including:
AD Joined → Microsoft Entra ID Join
Hybrid Microsoft Entra Joined → Microsoft Entra ID Join
Microsoft Entra tenant → Microsoft Entra tenant
The migration is performed in place without wiping or reimaging Windows, while preserving the existing user profile, applications, settings, and local files.
For administrators evaluating an in-place approach, the important point isn't simply whether a tool can change the join state.
You should also evaluate:
- readiness validation
- profile continuity
- Intune re-enrollment
- application behavior
- remote-device support
- migration logging
- rollback/recovery planning
- post-migration validation
Those operational details are what determine whether a migration approach works at enterprise scale.
Final thought
Moving to Microsoft Entra Join should be treated as an endpoint modernization project, not simply an identity switch.
The technical join operation may be relatively small.
Understanding everything that depends on the existing device identity is the harder part.
Assess the environment first, choose the migration method based on the condition of the devices, validate it with representative users, and then expand the deployment in controlled waves.
That approach makes the transition considerably easier to manage.

For teams planning this move, I’d make user continuity a key part of the pilot. Can users sign in, access their existing files and use their everyday applications afterward? I’d also check Intune enrolment, security policies and recovery access. Starting with a small mix of office and remote devices can help identify issues before a wider rollout.
