Function Copy-SqlEndpoint
{
<#
.SYNOPSIS
Copy-SqlEndpoint migrates server endpoints from one SQL Server to another.
 
.DESCRIPTION
By default, all endpoints are copied. The -Endpoints parameter is autopopulated for command-line completion and can be used to copy only specific endpoints.
 
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 greater.
 
.PARAMETER Destination
Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater.
 
.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 WhatIf
Shows what would happen if the command were to run. No actions are actually performed.
 
.PARAMETER Confirm
Prompts you for confirmation before executing any changing operations within the command.
 
.PARAMETER Force
Drops and recreates the endpoint if it exists

.EXAMPLE
Copy-SqlEndpoint -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
Copy-SqlEndpoint -Source sqlserver2014a -Destination sqlcluster -Endpoint tg_noDbDrop -SourceSqlCredential $cred -Force
 
Copies a single endpoint, 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
Copy-SqlEndpoint -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force
 
Shows what would happen if the command were executed using force.
