Scenario

Solution 1Recommended

Escalate the Regional Migration Request via Microsoft 365 Support

Because tenant and regional migrations require backend intervention from Microsoft, you must escalate your existing support ticket to the specialized Viva Engage team.

Network regional moves cannot be performed manually through the admin interface. If frontline support is unable to assist, the request must be escalated specifically to the Yammer/Viva Engage backend engineering team.

1
Request escalation from your current agent

Reply directly to the Microsoft support agent currently handling your ticket. Explicitly request that the ticket be escalated to the 'Viva Engage Product Team' for a regional network transfer.

2
Open a new Severity C Service Request

If the current agent is unresponsive, navigate to the Microsoft 365 admin center. Go to Support > Help & support, and open a new Severity C service request. In the description, reference your original ticket number and clearly state that the regional migration is blocking your deployment.

3
Utilize Microsoft Tech Community channels

Post your issue in the official Viva Engage community forums or submit feedback via the Microsoft 365 portal to gain additional visibility from Microsoft community managers.

Deployment Hold: Do not begin adding users or data to the Viva Engage network until the regional migration is fully completed, as transferring populated networks is significantly more complex.

Frequently Asked Questions

Why was my Yammer network created in the US instead of the EU?

By default, Yammer networks are often provisioned based on the legacy configuration of the Microsoft 365 tenant or if the tenant was originally set up with a billing address outside the EU.

Can I manually change my Viva Engage data location in the admin center?

No. Data residency moves for Yammer and Viva Engage require specialized backend migration processes that only Microsoft Support engineers can execute.

Will transferring the region delete my existing Yammer data?

If the network is completely empty, the migration is straightforward. For populated networks, Microsoft has specific data migration protocols, but it is highly recommended to finalize the region transfer before beginning your Viva Engage deployment.
