Azure migration

[Venkateswaran_tr]

Current Scenario: Single forest multiple Sub domain (child domains) and tree. Microsoft 365 in place.

Requirement: customer wants to migrate his tree domain separate from the forest, customer wants to migrate users and computers to azure since they have already having azure tenant which is used for Microsoft 365, Servers and other applications to on premises ADDS forest. customer is having SCCM in places features used are patch management, application deployment and OS image deployment etc.

Question: how to migrate users and computers to Azure tenant (to existing Microsoft 365 tenant) and maintaining the application/Server access since both application/server also migrating to new on premises ADDS forest (maintaining the SID history)

You almost need to do some testing:
SCCM will need a certificate, you could try the following instructions for workgroup clients: https://systemcenterdudes.com/sccm-client-install-workgroup-computers/
For App deployment of devices, patch management etc, you could look at the Cloud Gateway:
https://docs.microsoft.com/en-us/mem/configmgr/core/clients/manage/cmg/plan-cloud-management-gateway

And aim to replace SCCM and integrate with Endpoint Manager etc.

For profile migration, you could use the User Profile Wizard to migrate domain to Azure AD user profile (I believe it also migrates the SID, but you would have to test):
