function Copy-DbaCustomError { <# .SYNOPSIS Copy-DbaCustomError migrates custom errors (user defined messages), by the custom error ID, from one SQL Server to another. .DESCRIPTION By default, all custom errors are copied. The -CustomError parameter is auto-populated for command-line completion and can be used to copy only specific custom errors. If the custom error already exists on the destination, it will be skipped unless -Force is used. The us_english version must be created first. If you drop the us_english version, all the other languages will be dropped for that specific ID as well. .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. 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 2000 or higher. .PARAMETER DestinationSqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER CustomError The custom error(s) to process. This list is auto-populated from the server. If unspecified, all custom errors will be processed. .PARAMETER ExcludeCustomError The custom error(s) to exclude. This list is 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 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. .PARAMETER Force If this switch is enabled, the custom error will be dropped and recreated if it already exists on Destination. .NOTES Tags: Migration, CustomError 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-DbaCustomError .EXAMPLE PS C:\> Copy-DbaCustomError -Source sqlserver2014a -Destination sqlcluster Copies all server custom errors from sqlserver2014a to sqlcluster using Windows credentials.

If a custom error with the same name exists on sqlcluster, it will be updated because -Force was used. .EXAMPLE PS C:\> Copy-DbaCustomError -Source sqlserver2014a -Destination sqlcluster -ExcludeCustomError 60000 -Force Copies all the custom errors found on sqlserver2014a except the custom error with ID number 60000 to sqlcluster.
