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. For example, 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 higher.
 
        .PARAMETER SourceSqlCredential
            Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use:
 
            $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter.
 
            Windows Authentication will be used if SourceSqlCredential 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 Destination
            Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2012 or higher.
 
        .PARAMETER DestinationSqlCredential
            Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or 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 this switch is enabled, the SSIS Catalog will be dropped and recreated on Destination if it already exists.
 
        .PARAMETER Project
            Specifies a source Project name.
 
        .PARAMETER Folder
            Specifies a source folder name.
 
        .PARAMETER Environment
            Specifies an environment to copy.
 
        .PARAMETER EnableSqlClr
            If this switch is enabled and Destination does not have the SQL CLR configuration option enabled, user prompts for enabling it on Destination will be skipped. SQL CLR is required for SSISDB.
 
        .PARAMETER CreateCatalogPassword
            Specifies a secure string to use in creating an SSISDB catalog on Destination. If this is specified, prompts for the password will be skipped.
 
        .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.

        .EXAMPLE
            Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster
 
            Copies all folders, environments and SSIS Projects from sqlserver2014a to sqlcluster, using Windows credentials to authenticate to both instances. 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 to authenticate to sqlserver2014a and Windows credentials to authenticate to 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. User prompts for creating the catalog on Destination will be bypassed.
