# 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)
3. **Save** and close the Settings.xml.
4. Right-click **DecisionsServerInstaller.exe** and select **Run as administrator**. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2022-02-16_14h35_44.png)
5. From the **Decisions** **Installer**, select RESTART SERVICE. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2025-06-30_11h17_14(1).png)
6. After the **Decisions** **Service** restarts, open and log into the **Decisions** **Studio**/**User** **Portal** for the respective database. Then, verify the presence of the **System > Hosting Folder**. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/hosting%20photoshop.png)
