+# Data migration
+
+From v4.0.26 onwards, scripts are included for exporting and importing data of individual guilds.
+This allows migrating between databases or instances of the bot.
+
+## Exporting data
+
+To dump a single guild's data, run the following command in the bot's base directory:
+
+=== "npm"
+    ```bash linenums="0"
+    npm run bot.export -- -g <guild_id>
+    ```
+=== "pnpm"
+    ```bash linenums="0"
+    pnpm run bot.export -g <guild_id>
+    ```
+
+Note that this command requires the database and encryption key environment variables to be set.
+This command writes a single file and prints the path to it.
+
+!!! example
+    ```bash linenums="0"
+    $ npm run bot.export -- -g 810934178946351174
+
+    > discord-tickets@4.0.26 bot.export
+    > node scripts/export.mjs -g 810934178946351174
+
+    ✔ Connected
+    ✔ Exported settings
+    ✔ Exported 3 categories
+    ✔ Exported 1 tags
+    ✔ Exported 9 tickets
+    ✔ Written to "/home/container/user/dumps/80b5069d711591431db37f6a22742c73c1df44.dump"
+    ```
+
+!!! danger
+    The file is lightly encrypted but **the encryption key is the guild ID**.
+    Do not share the file publicly.
+
+!!! warning
+    **Do not rename the file.** The filename is a hash of the guild ID and must not be changed for the import script to work.
+
+## Importing data
+
+If moving from another instance, copy the guild's dump file into `user/dumps`.
+
+Run the following command in the bot's base directory:
+
+=== "npm"
+    ```bash linenums="0"
+    npm run bot.import -- -g <guild_id>
+    ```
+=== "pnpm"
+    ```bash linenums="0"
+    pnpm run bot.import -g <guild_id>
+    ```
+
+## Migrating from SQLite
+
+The data migration scripts can be used to move from SQLite to another database.
+
+1. [Export](#exporting-data) all guilds
+2. Modify the [`DB_PROVIDER`](configuration.md#db_provider) and [`DB_CONNECTION_URL`](./configuration.md#db_connection_url) environment variables
+3. Run `npm run postinstall`
+4. [Import](#importing-data) all guilds
