Function Copy-SqlPolicyManagement { <# .SYNOPSIS Migrates SQL Policy Based Management Objects, including both policies and conditions. .DESCRIPTION By default, all policies and conditions are copied. If an object already exist on the destination, it will be skipped unless -Force is used. The -Policies and -Conditions parameters are autopopulated for command-line completion and can be used to copy only specific objects. THIS CODE IS PROVIDED "AS IS", WITH NO WARRANTIES. .PARAMETER Source Source SQL Server.You must have sysadmin access and server version must be SQL Server version 2008 or higher. .PARAMETER Destination Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher. .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. .PARAMETER Force If policies exists on destination server, it will be dropped and recreated. .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.
