Is it possible to delete TM Profile in PME Sub and create with the same name in Corp Sub

Question

Is it possible to delete TM Profile in PME Sub and create with the same name in Corp Sub

Mohsin Javaid Baig (Lumovy Technology Solutions) 0 Microsoft External Staff

I deleted a traffic manager profile from a subscription in PME tenant, but when I tried to create a new one with same name in another subscription in Corp tenant I saw below error.

Label '<TM Profile Name>' is not available in '<TM Profile Name>.trafficmanager.net'. Please choose a different label and retry the operation.

I waited for more than 30 mins after deleting the TM profile from PME tenant hoping it might become available after some time, but it wasn't the case and I faced the same.

Is there any time period for which Azure holds the TM profile name before it can be created in another subscription (in different tenant)?

Hello @Mohsin Javaid Baig (Lumovy Technology Solutions)

Thank you for reaching Microsoft Q&A platform.

The Traffic Manager profile name (<TM Profile Name>.trafficmanager.net) must be globally unique across all Azure tenants, not just within a subscription.

When a Traffic Manager profile is deleted, the corresponding DNS label is not released immediately. This is because the name is managed within Microsoft’s global DNS infrastructure, and it may remain reserved for some time after deletion. As a result, attempting to reuse the same name (especially across different tenants) may continue to show it as unavailable.

Currently, there is no officially documented fixed timeframe for when the DNS label becomes available again. In practice, it can take some additional time beyond a few minutes for the name to be fully released.

Recommended next steps:

Please allow some additional time and try again later.

Alternatively, you may use a different name to proceed immediately.

Thank you @Sindhuja Dasari

Actually, we are moving out our service from PME tenant to Corp tenant and want to use the same endpoint, which is why we need to create the TM profile in Corp tenant with the same name. Since our service will be down for the time period till that label becomes available, we need to communicate this to the users. Is there any approximate number? e.g. 1-2 hours or less than 4 hours or more than that?

Hello @Mohsin Javaid Baig (Lumovy Technology Solutions)

I understand the need to estimate downtime for your migration.

While Azure does not provide a fixed SLA for DNS label release, based on observed behaviour of Traffic Manager (which uses a globally unique DNS name across all tenants), the name is not released immediately after deletion and may remain reserved for some time.

Approximate expectation for planning

In many cases, the name becomes available within a few hours

However, to avoid impact due to reattempts, it is recommended to plan for up to 24 hours in worst cases

Since you are moving across tenants and need to reuse the exact same endpoint:

A short window such as 30–60 minutes is typically not sufficient

For user communication, it is safer to indicate: “a few hours, with a potential extension up to 24 hours if the name is still reserved”

Thank you @Sindhuja Dasari for the information, we will plan accordingly. But there is another concern.

I added my Corp tenant App Service as an external endpoint to a PME tenant Traffic Manager Profile. Which correctly generated a Custom Domain record in my App Service. But when I deleted the same endpoint from Traffic Manager Profile, it didn't remove the record from Custom Domain, I even deleted the Traffic Manager Profile itself but record in Custom Domain is still there. How can I delete this record from custom domain now? When I try to delete it manually, I see below error.

This is expected. After a Traffic Manager profile is deleted, its trafficmanager.net label remains reserved to the original Microsoft Entra tenant. Subscriptions in that same tenant can reuse it immediately, but a different tenant cannot use it until the reservation expires.

Microsoft does not publish a fixed expiry time, so 30 minutes—or even 24 hours—cannot be used as a reliable migration window. There is no guaranteed zero-downtime way to transfer the exact Traffic Manager label between tenants by deleting and recreating it.

For a safe migration, create the new profile with a different label, validate its endpoints, and switch a custom DNS name that you control from the old profile to the new one after lowering its TTL in advance. Keep the old profile until DNS caches have expired. If clients have hard-coded the trafficmanager.net name, keep that profile in the original tenant and repoint its endpoints, or plan a maintenance window without a guaranteed duration.

Answer 1

Mohsin Javaid Baig (Lumovy Technology Solutions) hi & thx for sharing urs issue here at Q&A portal,

Yes, the same Traffic Manager DNS name can usually be reused after the original profile is deleted, even in another subscription or tenant. However, the label isn't always released immediately. Thirty minutes may not be enough. The deletion has to propagate through the Traffic Manager control plane and global DNS registration system, and the name can remain unavailable for some time after the resource disappears from the portal. First confirm that the old profile is fully deleted and not still present in another subscription, tenant, or resource group. Also check the old subscription’s Activity Log to make sure the delete operation completed successfully.

If the name is still unavailable after several hours, this may be a stale or orphaned Traffic Manager label. There’s no customer-side command to force its release. Open an Azure Traffic Manager support case with the old and new subscription IDs, profile name, deletion timestamp, and the correlation IDs for both the delete and failed create operations. The Traffic Manager team can confirm whether the label is still reserved and release it from the backend.
