Risks and Considerations When Migrating Yammer to Native Mode

Product: Microsoft 365
Device & OS: not provided
Scenario: Planning an organizational Yammer network migration to Microsoft 365 Native Mode.
Observed behavior: The migration process fundamentally alters Microsoft 365 integration, group management, user identity, and compliance policies, requiring careful evaluation before execution.

Before you start

Ensure you have Microsoft 365 Global Administrator permissions to access the Yammer admin center, run network alignment reports, and execute the migration.

Solution 1Recommended

Phase 1: Assess Requirements and Identify Network Impact

Evaluate your current Yammer network against Microsoft's Native Mode requirements to identify potential group and identity disruptions.

Moving to Native Mode requires all Yammer users to be in Microsoft Entra ID (formerly Azure AD) and all groups to be Microsoft 365 connected. Assessing these prerequisites is crucial to avoid data loss.

Review Current Requirements

Check Microsoft's official documentation for the latest Native Mode prerequisites, ensuring your organization supports Microsoft 365 group creation.

Identify Affected Communities

Audit your existing Yammer communities to determine which ones are unlisted, external, or not currently connected to Microsoft 365 Groups. These communities will be impacted during the transition.

Audit Administrators

Review your network administrators. Ensure they possess the necessary global admin or group creation privileges in Microsoft 365 to manage the newly connected groups post-migration.

Phase 1: Assess Requirements and Identify Network Impact

Alignment Report: Running the Microsoft 365 Alignment Report in the Yammer admin center will provide a detailed spreadsheet of users and groups that require attention before migrating.

Phase 2: Backup, Test, and Communicate Changes

Safeguard unaligned data and prepare your organization's users for the impending operational changes.

Frequently Asked Questions

What exactly does Yammer Native Mode mean?

Native Mode ensures that all Yammer users, groups, and files are directly tied to Microsoft Entra ID (Azure AD) and Microsoft 365 groups. This alignment provides a unified administrative experience, allowing Yammer to utilize standard Microsoft 365 compliance and eDiscovery features.

Will I lose files during the Yammer to Native Mode migration?

Files stored in Yammer groups that successfully connect to Microsoft 365 will be automatically moved to the group's SharePoint document library. However, files in groups that cannot be transitioned (like legacy unlisted groups without owners) may be at risk. It is crucial to back up this data beforehand.

How long does the Native Mode alignment process take?

The duration of the alignment process varies significantly based on the size of your network, the number of user accounts, and the volume of files to be migrated to SharePoint. For large enterprise networks, the process can take anywhere from a few hours to several days to fully complete.
