function Copy-DbaAgentAlert { <# .SYNOPSIS Copy-DbaAgentAlert migrates alerts from one SQL Server to another. .DESCRIPTION By default, all alerts are copied. The -Alert parameter is auto-populated for command-line completion and can be used to copy only specific alerts. If the alert 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 Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter. Windows Authentication will be used if SourceSqlCredential 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 Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or 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 Alert The alert(s) to process. This list is auto-populated from the server. If unspecified, all alerts will be processed. .PARAMETER ExcludeAlert The alert(s) to exclude. This list is auto-populated from the server. .PARAMETER IncludeDefaults Copy SQL Agent defaults such as FailSafeEmailAddress, ForwardingServer, and PagerSubjectTemplate. .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 Alert will be dropped and recreated on Destination. .PARAMETER Silent If this switch is enabled, the internal messaging functions will be silenced. .NOTES Tags: Migration, Agent Author: Chrissy LeMaire (@cl), netnerds.net Requires: sysadmin access on SQL Servers Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Copy-DbaAgentAlert .EXAMPLE Copy-DbaAgentAlert -Source sqlserver2014a -Destination sqlcluster Copies all alerts from sqlserver2014a to sqlcluster using Windows credentials. If alerts with the same name exist on sqlcluster, they will be skipped. .EXAMPLE Copy-DbaAgentAlert -Source sqlserver2014a -Destination sqlcluster -Alert PSAlert -SourceSqlCredential $cred -Force Copies a only the alert named PSAlert from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If a alert with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used. .EXAMPLE Copy-DbaAgentAlert -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force Shows what would happen if the command were executed using force. #> [cmdletbinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $true)] param ( [parameter(Mandatory = $true)] [DbaInstanceParameter]$Source, [PSCredential] $SourceSqlCredential, [parameter(Mandatory = $true)] [DbaInstanceParameter]$Destination, [PSCredential] $DestinationSqlCredential, [object[]]$Alert, [object[]]$ExcludeAlert, [switch]$IncludeDefaults, [switch]$Force, [switch]$Silent ) begin { $sourceServer = Connect-SqlInstance -SqlInstance $Source -SqlCredential $SourceSqlCredential $destServer = Connect-SqlInstance -SqlInstance $Destination -SqlCredential $DestinationSqlCredential $source = $sourceServer.DomainInstanceName $Destination = $destServer.DomainInstanceName } process { $serverAlerts = $sourceServer.JobServer.Alerts $destAlerts = $destServer.JobServer.Alerts if ($IncludeDefaults -eq $true) { if ($PSCmdlet.ShouldProcess($Destination, "Creating Alert Defaults")) { $copyAgentAlertStatus = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Name = "Alert Defaults" Type = "Alert Defaults" Status = $null DateTime = [Sqlcollaborative.Dbatools.Utility.DbaDateTime](Get-Date) } try { Write-Message -Message "Creating Alert Defaults" -Level Verbose $sql = $sourceServer.JobServer.AlertSystem.Script() | Out-String $sql = $sql -replace [Regex]::Escape("'$source'"), "'$Destination'" Write-Message -Message $sql -Level Debug $null = $destServer.Query($sql) $copyAgentAlertStatus.Status = "Successful" } catch { $copyAgentAlertStatus.Status = "Failed" $copyAgentAlertStatus Stop-Function -Message "Issue creating alert defaults." -Category InvalidOperation -InnerErrorRecord $_ -Target $destServer -Continue } $copyAgentAlertStatus } } foreach ($serverAlert in $serverAlerts) { $alertName = $serverAlert.name $copyAgentAlertStatus = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Name = $alertName Type = "Agent Alert" Status = $null DateTime = [Sqlcollaborative.Dbatools.Utility.DbaDateTime](Get-Date) } if ($Alert -and $Alert -notcontains $alertName -and $ExcludeAlert -contains $alertName) { continue } if ($destAlerts.name -contains $serverAlert.name) { if ($force -eq $false) { $copyAgentAlertStatus.Status = "Skipped" $copyAgentAlertStatus Write-Message -Message "Alert [$alertName] exists at destination.
