Function Copy-SqlAudit { <# .SYNOPSIS Copy-SqlAudit migrates server audits from one SQL Server to another. .DESCRIPTION By default, all audits are copied. The -Audits parameter is autopopulated for command-line completion and can be used to copy only specific audits. If the audit 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 greater. .PARAMETER Destination Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SourceSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $dcred = Get-Credential, then pass this $dcred to the -DestinationSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .NOTES Author: Chrissy LeMaire (@cl), netnerds.net Requires: sysadmin access on SQL Servers dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.

If audits with the same name exist on sqlcluster, they will be skipped. .EXAMPLE Copy-SqlAudit -Source sqlserver2014a -Destination sqlcluster -Audit tg_noDbDrop -SourceSqlCredential $cred -Force Copies a single audit, the tg_noDbDrop audit from sqlserver2014a to sqlcluster, using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster.
