Installing Icinga for Windows on systems that already have Icinga installed

Hi,

I have installed the Icinga agent through different ways in the past (installation package and early version of the Icinga Powershell Framework) but would now like to get them all to the same level.

Since Icinga for Windows and the Icinga Powershell Framework seem to be very mature now, I installed the framework using the new powershell script in

github.com

Icinga/icinga-powershell-framework/blob/master/doc/110-Installation/01-Getting-Started.md

# Getting Started - Icinga for Windows

Icinga for Windows provides tools and functionality to entirely manage itself. This includes first-time deployment including later installation of new components or updating installed ones. To ensure a smooth setup procedure, we recommend using the by Icinga provided scripts and repositories as baseline for deployment inside environments.

## Requirements

* Windows 2012 R2 or later
* PowerShell Version 4.0 or later
* [Execution Policies](https://docs.microsoft.com/de-de/powershell/module/microsoft.powershell.core/about/about_execution_policies) allowing module/script execution
* Access to [packages.icinga.com](https://packages.icinga.com) at least from one location

## Installation Dependencies

In order to install Icinga for Windows as easy as possible, we will require at least from one location access to [packages.icinga.com](https://packages.icinga.com). On this page we can find the sub-section [IcingaForWindows](https://packages.icinga.com/IcingaForWindows), which contains an installation script [IcingaForWindows.ps1](https://packages.icinga.com/IcingaForWindows/IcingaForWindows.ps1) and our repositories we can fetch our components, including the [Icinga PowerShell Framework](https://github.com/Icinga/icinga-powershell-framework) from.

**Note:** If you already installed Icinga for Windows, you can synchronize the existing repository from [packages.icinga.com](https://packages.icinga.com/IcingaForWindows) and download and paste the [IcingaForWindows.ps1](https://packages.icinga.com/IcingaForWindows/IcingaForWindows.ps1) with our synced content to an internal webserver, network share or locally on systems. The next steps can then be adjusted depending on your locations.

## Install Icinga for Windows

To install Icinga for Windows from systems with internet access, we can simply run this short PowerShell code inside an `administrative` PowerShell, to download the [IcingaForWindows.ps1](https://packages.icinga.com/IcingaForWindows/IcingaForWindows.ps1) and execute it afterwards:

this worked fine (regardless of whether the machine already has an agent and/or powershell framework installed, but I seems that when doing the core installation in IMC, it will not pick up on my current agent configuration. If i then fill out the configuration, the IMC will note an error, saying that it can not overwrite my configuration files, but everything else seems to be fine.

Is there a better/more correct way to get all my clients to the latest Powershell Framework/Agent versions?
