# Upgrade 4.x to 5.x {#upgrade-4-x-to-5-x}

Starting with 5.x the composer package name and extension key has been renamed!

You need to migrate the extension settings from
`['TYPO3_CONF_VARS']['EXTENSIONS']['wv_deepltranslate']` to
`['TYPO3_CONF_VARS']['EXTENSIONS']['deepltranslate_core']`.

Then you will need to replace the previous package by uninstalling it first.

## composer-mode {#composer-mode}

```bash
composer remove "web-vision/wv_deepltranslate"
composer require "web-vision/deepltranslate-core":"^5"
```

## classic-mode {#classic-mode}

1.  **Uninstall "wv_deepltranslate" using the Extension Manager**.
    Switch to the module **Admin Tools > Extensions** and filter for
    **wv_deepltranslate** and remove (uninstall) the extension.
1.  **Ensure to remove the folder completely**.
    Run

    ```bash
    rm -rf typo3conf/ext/wv_deepltranslate
    ```
1.  **Get it from the Extension Manager**:
    Switch to the module **Admin Tools > Extensions**.
    Switch to **Get Extensions** and search for the extension key
    *deepltranslate_core* and import the extension from the repository.
1.  **Get it from typo3.org**:
    You can always get current version from [TER](https://extensions.typo3.org/extension/deepltranslate_core) by downloading the zip
    version. Upload the file afterwards in the Extension Manager.
