The Teams admin center is transitioning to app-centric management, with migrations resuming mid-November 2024. Phase 1 auto-migration is delayed to early 2025, while Phase 2 allows administrators to self-initiate migration using a wizard. Detailed documentation is provided, and the process is designed to have no downtime.
Updated October 24, 2024: The migration to app-centric management using the Migration Wizard (referenced as Phase 2 in this post) is expected to resume by mid-November 2024. At that time, administrators will be able to self-initiate the migration using the wizard. The automatic migration for customers with only a global permission policy (Phase 1) and those with multiple permission policies (Phase 3) will be postponed until early 2025. Further updates, including the details for Phase 3 auto-migration, will be provided in a future MC post update and public documentation.
App centric management (ACM) is on hold as of August 14, 2024, and will restart in mid-October (previously mid-September). Your experience during this hold will fall under one of the following, with Phases defined in detail below.
What is in Phase 2?
Detailed documentation for the migration process is available at App centric management to manage user access to Teams apps - Microsoft Teams | Microsoft Learn.
App centric management introduces new admin settings to control who in the tenant can install Teams apps. First, admins can set a default value for new apps that are published to the Teams app store. Second, admins can manage apps for users, groups, or everyone in the organization. This feature replaces the existing app permission policies and provides admins with the ability to manage access to the app individually. The app permission policies for existing customers are migrated to maintain existing app availability in the tenant.

When this will happen:
This feature will gradually roll out across three major phases.
Phase 1 (from late November 2023 to early November 2024 (previously late September) affects the tenants that use only the Global app permission policy and have no custom app permission policies. The app status from the permission policy and tenant settings will be migrated to preserve the admin intent. The migration will not affect the end users and their ability to use the apps. Admins may see the Manage apps page in a read-only mode for a short time.
Phase 2 (from late May 2024 to early November 2024 (previously late September)) affects the tenants that use both global and custom app permission policies. This phase will let the admin choose to migrate to app centric management by following a migration process that will change the existing app permission policies to app assignments in the new app centric model. The admins will have the choice to modify the apps that are assigned using the custom permission policies to be accessible to groups, if they want.
Phase 3 (early 2025) applies to the tenants that skipped the migration in phase 1 or 2. These tenants will be migrated automatically in this phase. More details to come as a follow up MC post.
How this will affect your organization:
Starting with this release, you can:
1. Manage Teams apps for selected set of users, groups or all users in the organization.
2. Set the default value for new apps published to Teams app store for each of the app types: Microsoft, third-party and custom apps.
What you need to do to prepare:
No action needed for phase 1 tenants with Global permission policy only. More information will be provided for phase 2 and 3 tenants in a follow-up communication before launch.
