Import and export SSIS Catalog Environments with JSON

Case
I want to import and export Environments to/from my SSIS Catalog. Doing it manually in SSMS takes ages. How can you do that more quickly?
I want to export this environment



















Solution
I will ago I created a couple of PowerShell scripts to deploy environments to your SSIS Catalog with a CSV file, database table or an array as source. The script below is a follow up that allows you to export one or more environments as json files, but also has an import method to deploy those exported environments to a Catalog: Get-CatalogEnvironment and Set-CatalogEnvironment.

This is an example of how you execute the two methods. It first starts with importing a separate script file with various methods and then you can either execute the Get or the Set method:
# PowerShell code
# If you have trouble executing a PowerShell due an Execution Policy then run
# the following script. Note that you need to run PowerShell as administrator
# More information: https://technet.microsoft.com/nl-nl/library/ee176961.aspx
# Set-ExecutionPolicy Unrestricted 

# Include functions from a secondairy file
. "$PSScriptRoot\Ssisfunctions.ps1"

# Download example
Get-CatalogEnvironment -SsisServer "mySqlServer\myInstance" -ExportPath "c:\backup\" -FolderName MyEnvFolder -EnvironmentName MyEnvName -Verbose

# Upload example
Set-CatalogEnvironment -SsisServer "mySqlServer\myInstance" -FolderName MyEnvFolder -EnvironmentName MyEnvName -ImportFilePath "C:\temp\employees.json" -DeleteExistingEnvironment $true -Verbose
Example of execution














The environment json files look like this:
[
    {
        "Name":"FolderStageFiles",
        "Description":"Location of stage files",
        "Type":"String",
        "Sensitive":false,
        "Value":"d:\\sources\\"
    },
    {
        "Name":"FtpPassword",
        "Description":"Secret FTP password",
        "Type":"String",
        "Sensitive":true,
        "Value":$3cr3t
    },
    {
        "Name":"MIS_STG_Connectionstring",
        "Description":"Connectionstring to stage database",
        "Type":"String",
        "Sensitive":false,
        "Value":"Data Source=.\\sql2016;Initial Catalog=MIS_STG;Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;"
    },
    {
        "Name":"NumberOfRetries",
        "Description":"Number of retries for Webservice Task",
        "Type":"Int16",
        "Sensitive":false,
        "Value":3
    }
]

You can also get detailed help information and instructions with the standard PowerShell method. Get-Help. It allows you to see examples or the see which parameter is mandatory or optional.
# PowerShell code
# Getting help about the commands
Get-Help Set-CatalogEnvironment -detailed
Get-Help Get-CatalogEnvironment -example

And this is the content of the Ssisfunctions.ps1 file containing the various methods. Take a look and let me know if you have any improvements
# PowerShell code: Ssisfunctions.ps1 (v0.1)

.Synopsis
    Download one or more environments from an SSIS Catalog as JSON files

.DESCRIPTION
    This functions allows you to download an Environment from the SSIS Catalog. By leaving out the foldername or environmentname you can also download
    multiple files. All files are downloaded as JSON files in the format [FolderName].[EnvironmentName].json
    Example file of export:

    [
       {
          "Name":"FolderStageFiles",
          "Description":"Location of stage files",
          "Type":"String",
          "Sensitive":false,
          "Value":"d:\\sources\\"
       },
       {
          "Name":"FtpPassword",
          "Description":"Secret FTP password",
          "Type":"String",
          "Sensitive":true,
          "Value":null
       },
       {
          "Name":"MIS_STG_Connectionstring",
          "Description":"Connectionstring to stage database",
          "Type":"String",
          "Sensitive":false,
          "Value":"Data Source=.\\sql2016;Initial Catalog=MIS_STG;Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;"
       },
       {
          "Name":"NumberOfRetries",
          "Description":"Number of retries for Webservice Task",
          "Type":"Int16",
          "Sensitive":false,
          "Value":3
       }
    ]

.PARAMETER SsisServer
    Mandatory: The name of the SQL Server instance that runs the SSIS Catalog

.PARAMETER FolderName
    Optional: The name of the Catalog folder that contains the Environment

.PARAMETER EnvironmentName
    Optional: The name of the Environment

.PARAMETER ExportPath
    Optional: The fully qualified path where the json files will be saved. Default value: c:\temp\

.PARAMETER Verbose
    Optional: Get more logging information on the screen

.EXAMPLE
    Get-CatalogEnvironment -SsisServer "myServer\myInstance" -ExportPath "c:\backup\" -FolderName myCatalogFolder -EnvironmentName myEnvironmentName

.EXAMPLE
    Get-CatalogEnvironment -SsisServer "myServer\myInstance" -ExportPath "c:\backup\" -Verbose

.NOTES
    You cannot get the value of sensitive variables.The value will be NULL in the export file. 
    Current scripts works for SSIS 2016. Change version number in code to use an other version of SSIS.

    Write-Host "Finished, total inserts $($InsertCount)  and total updates $($UpdateCount)"
}

Later on I will add various extra methods for example to test the existence of an environment, to delete an environment, to move an environment, to copy an environment, to rename an environment or to connect an environment to a project. Please let me know if you have any suggestions for extra functionality or improvements!
