Breaks database mirroring partnerships and stops mirroring sessions
Terminates database mirroring sessions by breaking the partnership between principal and mirror databases. This command stops the mirroring relationship completely, which is useful when decommissioning mirrors, performing maintenance that requires breaking the partnership, or during disaster recovery scenarios where you need to bring a database online independently.
Important: This function only breaks the mirroring partnership - it does not automatically recover databases that are left in a "Restoring" state. You'll need to manually restore those databases with RECOVERY to make them accessible for normal operations.

The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function
to be executed against multiple SQL Server instances.
Alias | |
Required | False |
Pipeline | false |
Default Value |
Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.
Alias | |
Required | False |
Pipeline | false |
Default Value |
Specifies the names of databases whose mirroring partnerships should be terminated. Accepts multiple database names.
Required when using SqlInstance parameter. Use this to target specific mirrored databases rather than processing all databases on the instance.
Alias | |
Required | False |
Pipeline | false |
Default Value |
Accepts database objects from the pipeline, typically from Get-DbaDatabase.
Use this when you want to filter databases using Get-DbaDatabase's capabilities before breaking mirroring partnerships.

Required | False |
Pipeline | true (ByValue) |
Default Value |
By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
