# Change DB Type

{% hint style="danger" %}
This is only available if you're running version 1.2.8 or newer.
{% endhint %}

{% hint style="warning" %}
If you're coming from versions earlier than 1.2.8, you first need to [Migrate your Data to new format](https://nidzo-docs.gitbook.io/ultrabot/installation-and-setup/database/v1.2.8-migration).
{% endhint %}

To transfer data between different database types, you'll need to use `database-actions` addon, the same one that is used for **1.2.8** database format migration.

There are specific database pairs for moving data:

* SQLite > MySQL/MongoDB
* MySQL/MongoDB > SQLite

To transfer data from one database type to other, you need to:

1. [Download addon from this page](https://nidzo-docs.gitbook.io/ultrabot/installation-and-setup/database) and move folder from the zip into the `addons` folder (skip this if you already have addon installed)
2. Open `config.yml` from that addon folder and put your ID into the `transfer_access` field and make sure that `startup_migrate` is set to `false`
3. Open your bot's console so you can see if any error occur during the transfer
4. Run the `/transfer [Database From] [Database To]` command.\
   1\. Make sure that your `database.type` config field is set to the same database type as the one you're moving data from, if 'Database From' is MongoDB then `database.type` should be `mongo` etc.
5. After transfer is done, stop the bot and remove the addon
