Identifies databases running at lower compatibility levels than the SQL Server instance supports
Compares each database's compatibility level against the SQL Server instance's maximum supported compatibility level. This helps identify databases that may not be leveraging newer SQL Server features and performance improvements available after an instance upgrade. Returns detailed comparison results showing which databases could benefit from compatibility level updates to match the server version.

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 which databases to test for compatibility level mismatches. Accepts database names, wildcards, or arrays.
Use this when you need to check specific databases instead of testing all databases on the instance.
Alias | |
Required | False |
Pipeline | false |
Default Value |
Specifies which databases to skip during compatibility level testing. Accepts database names, wildcards, or arrays.
Use this to exclude system databases, maintenance databases, or any databases you don't want included in the results.

Required | False |
Pipeline | false |
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.
