# Breaking: #62983 - postProcessMirrorUrl signal has moved {#breaking-62983}

See [forge#62983](https://forge.typo3.org/issues/62983)

## Description {#description}

While refactoring the Language backend module, the
`TYPO3CMSLangServiceUpdateTranslationService::postProcessMirrorUrl` signal got lost. Due to
the refactoring, it has been integrated in another class.

## Impact {#impact}

Using the old signal will prevent the slot from being called.

## Affected Installations {#affected-installations}

All extensions are affected that use the old
`TYPO3CMSLangServiceUpdateTranslationService::postProcessMirrorUrl`
signal.

## Migration {#migration}

Change the slot to use the `TYPO3CMSLangServiceTranslationService::postProcessMirrorUrl`
signal. If it is required to serve multiple TYPO3 versions, use the following code:

```php
$signalSlotDispatcher->connect(
	version_compare(TYPO3_version, '7.0', '<')
		? 'TYPO3\\CMS\\Lang\\Service\\UpdateTranslationService'
		: 'TYPO3\\CMS\\Lang\\Service\\TranslationService',
	'postProcessMirrorUrl',
	'Vendor\\Extension\\Slots\\CustomMirror',
	'postProcessMirrorUrl'
);
```
