function Copy-DbaSsisCatalog {
    <#
.SYNOPSIS
Copy-DbaSsisCatalog migrates Folders, SSIS projects, and environments from one SQL Server to another.
 
.DESCRIPTION
By default, all folders, projects, and environments are copied.
The -Project parameter can be specified to copy only one project, if desired.
The parameters get more granular from the Folder level. i.e. specifying folder will only deploy projects/environments from within that folder.
 
.PARAMETER Source
Source SQL Server.You must have sysadmin access and server version must be SQL Server version 2012 or greater.
 
.PARAMETER Destination
Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2012 or greater.
 
.PARAMETER Force
Drops and recreates the SSIS Catalog if it exists
 
.PARAMETER Project
Specify a source Project name.
 
.PARAMETER Folder
Specify a source folder name.
 
.PARAMETER Environment
Specify an environment to copy over.
 
.PARAMETER EnableSqlClr
If the destination does not have SQL CLR configuration option enabled (which is required for SSISDB), providing this parameter will skip user prompts for enabling CLR on the destination.
 
.PARAMETER CreateCatalogPassword
If a destination SSISDB catalog needs to be created, specify this secure string parameter to skip password prompts.
 
.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 SourceSqlCredential
Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use:
 
$scred = Get-Credential, this pass $scred object to the param.
 
Windows Authentication will be used if DestinationSqlCredential is not specified. 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, this pass this $dcred to the param.
 
Windows Authentication will be used if DestinationSqlCredential is not specified. To connect as a different Windows user, run PowerShell as that user.

.EXAMPLE
Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster
 
Copies all folders, environments and all ssis Projects from sqlserver2014a to sqlcluster, using Windows credentials. If folders with the same name exist on the destination they will be skipped, but projects will be redeployed.
 
.EXAMPLE
Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster -Project Archive_Tables -SourceSqlCredential $cred -Force
 
Copies a single Project, the Archive_Tables Project from sqlserver2014a to sqlcluster, using SQL credentials for sqlserver2014a
and Windows credentials for sqlcluster. If a Project with the same name exists on sqlcluster, it will be deleted and recreated because -Force was used.
 
.EXAMPLE
Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force
 
Shows what would happen if the command were executed using force.
 
.EXAMPLE
$SecurePW = Read-Host "Enter password" -AsSecureString
Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster -CreateCatalogPassword $SecurePW
 
Deploy entire SSIS catalog to an instance without a destination catalog. Passing -CreateCatalogPassword will bypass any user prompts for creating the destination catalog.
