Cannot delete Service bus in Azure as it contains an issue

Hello David Cuervo,

Thank you for posting your question in the Microsoft Q&A forum.  

The error indicates you cannot delete the Azure Service Bus namespace because an active migration replication process is still underway, which places a protective lock on the resource to prevent data loss or corruption during transfer.

To resolve this, you must first navigate to the migration configuration within your Service Bus namespace in the Azure portal and explicitly abort the ongoing migration operation. Once the migration has been successfully terminated, the replication lock will be removed, allowing you to proceed with deleting the migration configuration itself. Only after these intermediary steps are completed will the namespace be released from its operational state, enabling you to perform the final deletion.

This process ensures data integrity is maintained by preventing accidental deletion during critical operations. If the abort action fails or the issue persists, contacting Azure support may be necessary to investigate potential backend state inconsistencies.

Thanks for reaching out on Microsoft Q&A and really appreciate your patience while we looked into this.

Also, a big thanks to Suwarna S Kale for already sharing the correct direction. The issue is indeed due to an active Service Bus migration replication process, which places a protective lock on the namespace and prevents its deletion. To resolve this, you must first abort or complete the migration. Once the migration is terminated, the lock will be removed, allowing you to proceed with deleting the namespace.

Solution Steps:

OPTION 1: Using the Azure Portal

1. Navigate to your Service Bus namespace in the Azure portal.
2. In the left-hand menu, under Settings, select Migrate.
3. On the migration page, you will see the status of the replication. If it is active, you will have an option to Abort Migration. Click this to terminate the process.
4. Once the migration is aborted, you can proceed to delete the namespace.

OPTION 2: You can do this either in the Azure portal or with the Azure CLI:

# Check migration status
az servicebus migration show -g <resource-group> -n <namespace>
# Abort migration
az servicebus migration abort -g <resource-group> -n <namespace>
# Or complete migration if you intend to finalize it
az servicebus migration complete -g <resource-group> -n <namespace>
# Delete migration config (if needed)
az servicebus migration delete -g <resource-group> -n <namespace>
# Finally, delete the namespace
az servicebus namespace delete -g <resource-group> -n <namespace>

In some cases, if there’s a geo-DR pairing, you may also need to break it manually before deletion:

az servicebus georecovery-alias break-pair -g <resource-group> --namespace-name <namespace> --alias <alias>
