# Deprecation: #86068 - old condition syntax {#deprecation-86068}

See [forge#86068](https://forge.typo3.org/issues/86068)

## Description {#description}

The Symfony expression language is available for TypoScript since [forge#85829](https://forge.typo3.org/issues/85829) has been merged.
Accordingly the classic TypoScript condition syntax has been marked as deprecated.

For detailed information about the new expression language see [#85829](https://docs.typo3.org/permalink/changelog:feature-85829).

## Impact {#impact}

Using the old condition syntax will trigger a PHP `E_USER_DEPRECATED` error.

Also the combination of multiple condition blocks with `AND`, `OR`, `&&` and `||` has been
marked as deprecated and will trigger a PHP `E_USER_DEPRECATED` error.

If it is not possible yet to fully migrate to Symfony expression language, the feature flag `[SYS][features][TypoScript.strictSyntax]`
can be disabled via Settings -> Configure Installation-Wide Options or directly in `LocalConfiguration.php`.

## Affected Installations {#affected-installations}

TYPO3 installations with extensions which define conditions using the old syntax or setups which
make use of the old condition syntax.

## Migration {#migration}

The old conditions can be replaced with the new expression language.
