考虑php7.3的冲突php5

我最近从PHP 7.2切换到7.3，启用时收到此消息，我不确定这是错误还是出于信息目的：

sudo a2enmod php7.3
Considering dependency mpm_prefork for php7.3:
Considering conflict mpm_event for mpm_prefork:
Considering conflict mpm_worker for mpm_prefork:
Enabling module mpm_prefork.
Considering conflict php5 for php7.3:
Enabling module php7.3.
To activate the new configuration, you need to run:
  service apache2 restart

我需要做什么吗？它在重启apache之后运行

你有解决方案吗？
