# Migrating a Standalone Database into a Multi-Tenant Instance

## Overview

**Multi-Tenancy** in v9 provides **Administrators**the flexibility and option to establish **Tenant****Instances**from any desire locations. This may be completed by installing a new **Version 9******Installation [Tenant Instance from scratch](https://documentation.decisions.com/v9/docs/multi-tenancy-adding-and-setting-up-a-tenant-instance), or by migrating a pre-existing standalone environment into a **Hosted****Tenant****Instance**. The latter allows the ability to create a Tenant Instance without losing any preexisting data or work contained by the migrated database. The following document demonstrates how to convert a **Standalone**(Unmanaged) **Database**into a Tenant (Hosted) Instance.

## Example

1. From the **Local****File****System**of the **Standalone****Database**navigate to **C:\Program Files\Decisions\Decisions Server** and open **Settings.xml**in a **Text****Editor**. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2022-02-16_14h29_32.png)
2. From Settings.xml, change the value in between the **<ServerType/>** tags from "Standard" to "Hosted". ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2022-02-16_14h32_02.png)
