# Updating Amplia on Windows Server

To update your instance of [Amplia](https://docs.lacunasoftware.com/en-us/articles/amplia), follow the instructions on that page.

> **Note**
>
> To see if an update will require changing any settings, look in the [Amplia changelog](https://docs.lacunasoftware.com/en-us/articles/amplia/changelog) for the configuration changes between the version you are installing and the version you are currently installing (to know how to check the installed version of the system, see [this article](https://docs.lacunasoftware.com/en-us/articles/amplia/on-premises/check-version) ).

> **Warning**
>
> Amplia 5.0 requires the ASP.NET Core 10.0 Hosting Bundle. If you are updating from a 4.x version, follow the steps on
> [Update Amplia from 4.x to 5.0](https://docs.lacunasoftware.com/en-us/articles/amplia/on-premises/update-50) first.

1. Stop the web site in IIS Manager.
1. Create a backup of database and site folder.
1. Extract the contents of the new package ([amplia-5.0.0.zip](https://cdn.lacunasoftware.com/amplia/amplia-5.0.0.zip)) to the site folder, overwriting all files.
1. Make any necessary changes to the file `appsettings.iis.json` (see note above on how to know which changes will be required).
1. Start the web site IIS Manager.

> **Note**
>
> The `appsettings.iis.json` file with your instance settings will be preserved, because in the package there is no file with that name.
