function Copy-DbaInstanceAuditSpecification { <# .SYNOPSIS Copy-DbaInstanceAuditSpecification migrates server audit specifications from one SQL Server to another. .DESCRIPTION By default, all audits are copied. The -AuditSpecification parameter is auto-populated for command-line completion and can be used to copy only specific audits. If the audit specification already exists on the destination, it will be skipped unless -Force is used. .PARAMETER Source Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher. .PARAMETER SourceSqlCredential 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. .PARAMETER Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher. .PARAMETER DestinationSqlCredential 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. .PARAMETER AuditSpecification The Server Audit Specification(s) to process. Options for this list are auto-populated from the server. If unspecified, all Server Audit Specifications will be processed. .PARAMETER ExcludeAuditSpecification The Server Audit Specification(s) to exclude. Options for this list are auto-populated from the server .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER Force If this switch is enabled, the Audits Specifications will be dropped and recreated on Destination. .PARAMETER 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. .NOTES Tags: Migration,ServerAudit,AuditSpecification Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Requires: sysadmin access on SQL Servers .LINK https://dbatools.io/Copy-DbaInstanceAuditSpecification .EXAMPLE PS C:\> Copy-DbaInstanceAuditSpecification -Source sqlserver2014a -Destination sqlcluster Copies all server audits from sqlserver2014a to sqlcluster using Windows credentials to connect.
