function Copy-DbaResourceGovernor { <# .SYNOPSIS Migrates Resource Pools .DESCRIPTION By default, all non-system resource pools are migrated. If the pool already exists on the destination, it will be skipped unless -Force is used. The -ResourcePool parameter is auto-populated for command-line completion and can be used to copy only specific objects. .PARAMETER Source Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher. .PARAMETER SourceSqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2008 or higher. .PARAMETER DestinationSqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER ResourcePool Specifies the resource pool(s) to process. Options for this list are auto-populated from the server. If unspecified, all resource pools will be processed. .PARAMETER ExcludeResourcePool Specifies the resource pool(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 policies 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, ResourceGovernor Author: Chrissy LeMaire (@cl), netnerds.net Requires: sysadmin access on SQL Servers Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Copy-DbaResourceGovernor .EXAMPLE Copy-DbaResourceGovernor -Source sqlserver2014a -Destination sqlcluster Copies all extended event policies from sqlserver2014a to sqlcluster using Windows credentials to connect to the SQL Server instances.. .EXAMPLE Copy-DbaResourceGovernor -Source sqlserver2014a -Destination sqlcluster -SourceSqlCredential $cred Copies all extended event policies from sqlserver2014a to sqlcluster using SQL credentials to connect to sqlserver2014a and Windows credentials to connect to sqlcluster. .EXAMPLE Copy-DbaResourceGovernor -Source sqlserver2014a -Destination sqlcluster -WhatIf Shows what would happen if the command were executed. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $true)] param ( [parameter(Mandatory = $true)] [DbaInstanceParameter]$Source, [PSCredential]$SourceSqlCredential, [parameter(Mandatory = $true)] [DbaInstanceParameter]$Destination, [PSCredential]$DestinationSqlCredential, [object[]]$ResourcePool, [object[]]$ExcludeResourcePool, [switch]$Force, [Alias('Silent')] [switch]$EnableException ) process { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential $destServer = Connect-SqlInstance -SqlInstance $Destination -SqlCredential $DestinationSqlCredential $sourceClassifierFunction = Get-DbaResourceGovernorClassifierFunction -SqlInstance $sourceServer $destClassifierFunction = Get-DbaResourceGovernorClassifierFunction -SqlInstance $destServer $copyResourceGovSetting = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Type = "Resource Governor Settings" Name = "All Settings" Status = $null Notes = $null DateTime = [DbaDateTime](Get-Date) } $copyResourceGovClassifierFunc = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Type = "Resource Governor Settings" Name = "Classifier Function" Status = $null Notes = $null DateTime = [DbaDateTime](Get-Date) } if ($Pscmdlet.ShouldProcess($destination, "Updating Resource Governor settings")) { if ($destServer.Edition -notmatch 'Enterprise' -and $destServer.Edition -notmatch 'Datacenter' -and $destServer.Edition -notmatch 'Developer') { Write-Message -Level Verbose -Message "The resource governor is not available in this edition of SQL Server.
