Not necessarily; php -v can still show PHP 7.3 after installing php@7.4 with Homebrew on macOS Catalina.

### Can installing PHP 7.4 from the Ondrej PPA affect FCGI?

One report says installing PHP 7.4 with the Ondrej PPA caused problems while websites ran under FCGI.

Migration can become urgent when hardware breaks or the host no longer physically provides the old PHP version. Upgrading PHP is hard, but regular maintenance is also required.
