Function Copy-SqlDataCollector
{
<#
.SYNOPSIS
Migrates user SQL Data Collector collection sets. SQL Data Collector configuration is on the agenda, but it's hard.
 
.DESCRIPTION
By default, all data collector objects are migrated. If the object already exists on the destination, it will be skipped unless -Force is used.
  
The -CollectionSets parameter is autopopulated for command-line completion and can be used to copy only specific objects.
 
THIS CODE IS PROVIDED "AS IS", WITH NO WARRANTIES.
 
.PARAMETER Source
Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher.
 
.PARAMETER Destination
Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher.
 
.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 Force
If collection sets exists on destination server, it will be dropped and recreated.
 
.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 NoServerReconfig
Upcoming parameter to enable server reconfiguration
