function Copy-DbaEndpoint {
<#
    .SYNOPSIS
        Copy-DbaEndpoint migrates server endpoints from one SQL Server to another.
 
    .DESCRIPTION
        By default, all endpoints are copied.
 
        If the endpoint 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
        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 Endpoint
        The endpoint(s) to process. This list is auto-populated from the server. If unspecified, all endpoints will be processed.
 
    .PARAMETER ExcludeEndpoint
        The endpoint(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, existing endpoints on Destination with matching names from Source will be dropped.

    .EXAMPLE
        PS C:\> Copy-DbaEndpoint -Source sqlserver2014a -Destination sqlcluster
 
        Copies all server endpoints from sqlserver2014a to sqlcluster, using Windows credentials. If endpoints with the same name exist on sqlcluster, they will be skipped.
 
    .EXAMPLE
        PS C:\> Copy-DbaEndpoint -Source sqlserver2014a -SourceSqlCredential $cred -Destination sqlcluster -Endpoint tg_noDbDrop -Force
 
        Copies only the tg_noDbDrop endpoint from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If an endpoint with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.
 
    .EXAMPLE
        PS C:\> Copy-DbaEndpoint -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force
 
        Shows what would happen if the command were executed using force.
