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.

-Database

The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed.

-ExcludeDatabase

The database(s) to exclude - this list is auto-populated from the server

-Threshold

Allows you to specify a minimum % of the seed range being utilized. This can be used to ignore seeds that have only utilized a small fraction of the range.

-ExcludeSystem

Allows you to suppress output on system databases

-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.
