Synopsis

Tests to see if it's possible to easily rename the server at the SQL Server instance level, or if it even needs to be changed.

Description

When a SQL Server's host OS is renamed, the SQL Server should be as well. This helps with Availability Groups and Kerberos.

This command helps determine if your OS and SQL Server names match, and whether a rename is required.

It then checks conditions that would prevent a rename, such as database mirroring and replication.

Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Optional Parameters

-SqlCredential

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.

-ExcludeSsrs

If this switch is enabled, checking for SQL Server Reporting Services will be skipped.

-EnableException

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.
