How the work unfolds

Milestone 1

Kickoff and scope confirmation — confirm source and target tenants, business drivers, user counts, migration waves, timing constraints, key stakeholders, and success criteria for the staged transition.

Milestone 2

Discovery and inventory — review users, groups, administrative roles, domains, identity synchronization dependencies, authentication methods, conditional access policies, enterprise applications, app registrations, and permission dependencies relevant to the transition.

Milestone 3

Transition design — define the staged migration approach, identity mapping, naming and UPN strategy, group and permission handling, coexistence requirements, pilot group, cutover windows, validation approach, and rollback or remediation checkpoints.

Milestone 4

Target tenant readiness — prepare the target Entra ID tenant configuration needed for the agreed scope, including baseline identity settings, administrative access, security configuration alignment, required domains or domain planning, and migration tooling readiness where applicable.

Milestone 5

Pilot stage — migrate or transition a controlled pilot group of users, groups, and permissions; validate sign-in, access, group membership, application access dependencies, and administrative visibility before broader rollout.

Milestone 6

Staged migration waves — execute approved migration waves for in-scope users, groups, permissions, and related Entra ID configurations, with progress tracking and issue remediation between waves.

Milestone 7

Cutover coordination — coordinate final identity, access, and configuration updates needed for each wave or final transition event, including user communication support and validation checkpoints.

Milestone 8

Validation and remediation — verify that migrated identities, groups, and permissions are present and functioning in the target tenant, review exceptions, and remediate issues within the agreed engagement scope.

Milestone 9

Knowledge transfer and closeout — provide a summary of completed activities, known exceptions, recommended next steps, and operational handover guidance for the client’s administrators.

Prerequisites

Authorized administrative access to both the source and target Microsoft Entra ID tenants, with roles sufficient to review and configure users, groups, domains, enterprise applications, app registrations, conditional access, and related identity settings within scope.

Limitations & technical notes

!Microsoft Entra ID tenant-to-tenant transitions are dependency-sensitive; application behavior, identity synchronization, domain configuration, and conditional access policies must be reviewed before each major phase.
!Object identifiers, service principal identifiers, group identifiers, and application relationships may differ between tenants; applications or scripts that depend on fixed object IDs may require updates by the application owner.
!User passwords are not migrated in plaintext. Password reset, temporary access, federation, synchronization, or other authentication transition methods may be required depending on the client’s identity model.
!A custom domain generally cannot be verified and actively used in two Microsoft Entra ID tenants at the same time, so domain and UPN cutover planning may require a controlled change window.
!Conditional access policies, MFA methods, authentication strength settings, named locations, privileged roles, and access reviews may require validation or recreation in the target tenant depending on tenant configuration and licensing.
!Guest users, external collaboration settings, cross-tenant access settings, B2B relationships, and partner integrations may not transfer one-for-one and may require separate review.
!App secrets, certificates, reply URLs, API permissions, admin consent, SCIM provisioning, and SSO settings may require application-owner action and testing.
!The staged approach is designed to minimize disruption, but it does not guarantee zero downtime or zero user impact; brief access interruptions may occur during cutover, domain, sign-in, or application configuration changes.
!Final scope, timing, and technical approach may vary based on tenant size, application complexity, identity synchronization architecture, security requirements, and Microsoft service limitations at the time of execution.

The service is planned to minimize business disruption and downtime, because it uses a phased approach and supports access to both old and new environments during transition. However, the service content does not guarantee zero downtime, so any downtime expectations, cutover windows, and rollback planning should be confirmed during scoping.

What are the prerequisites for the Entra ID Tenant-to-Tenant Staged Transition service?

The provided service content does not state a formal prerequisite list. Because tenant-to-tenant transitions depend on the source and target Microsoft Entra ID environments, buyers should confirm prerequisites such as administrative access, tenant readiness, identity inventory, application dependencies, and security requirements with IT Partner before engagement kickoff.

What happens during the engagement?

During the engagement, IT Partner creates a step-by-step migration plan and performs a phased transition of identities, Entra ID-related resources, configurations, users, groups, and permissions between Microsoft Entra ID tenants. The service is structured to support both source and target tenant access during the transition and reduce risk through staged execution.

What are IT Partner’s responsibilities in this service?

The detailed IT Partner responsibility list is not available in the provided service content, although the service deliverables include planning and executing the staged Entra ID tenant-to-tenant transition. Buyers should confirm the exact responsibility split with IT Partner, especially for tenant access, configuration changes, validation, communications, and post-transition support.

What are the client’s responsibilities during the transition?
