Converting Azure Registered device into hybrid azure ad joined

Hi Don,

Azure AD registered devices will not be converted but Hybrid Azure AD joined devices will be added to the devices-list in Azure AD.

Users will not experience any changes when devices are added as Hybrid Azure AD joined devices.

1. Microsoft Azure Active Directory Connect
- Additional tasks > Configure device options > Configure Hybrid Azure AD join > Windows 10 or later domain-joined devices > SCP configuration
- Sync setting > Domain/OU filtering > sync your devices (computer objects)
- PowerShell: Start-ADSyncSyncCycle -PolicyType inital

IMPORTANT: computer objects first have to be synced to Azure AD before they contact Azure AD to be enrolled!

2. Device prerequisites
- Windows 10/11 OS. Note that Windows Home editions are not supported!
- Line of sight of the domain controller(s) when being added as Hybrid Azure AD joined devices
- Please first test connectivity to Azure AD: https://learn.microsoft.com/en-us/samples/azure-samples/testdeviceregconnectivity/testdeviceregconnectivity
- Two regkeys must exist (this can be accomplished via GPO):
SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ\AAD >TenantId
SOFTWARE\Microsoft\Windows\CurrentVersion\CDJ\AAD >TenantName
- Reboot the devices to start the join-process or join the device via CMD > dsregcmd /join /debug

4. Device troubleshooting
- CMD > dsregcmd /status
- Event viewer > Applications and Services logs > Microsoft > Windows > User Device Registration > Admin
