Entra ID Migration vs Device Migration

A Microsoft Entra ID (formerly Azure AD) migration moves identities. A device migration moves the Windows computers people use. Most tenant-to-tenant and merger projects need both.

Identity migration creates or matches users and groups in the target tenant and keeps attributes and group memberships aligned while both tenants run. Mailbox and file content moves separately, with a data migration tool. (PowerSyncPro does not move data)

Device migration moves each Windows device from the source domain or tenant to the target. Without a migration tool, that usually means a wipe, a new profile and a rebuilt desktop. An in-place device migration keeps the user’s profile, files and applications, and reconnects the Microsoft 365 apps to the new tenant.

PowerSyncPro DirSync handles the identity side and builds the mapping between source and target accounts. PowerSyncPro Migration Agent uses that mapping to move each device in place.
