Hello,

I upgrade my PHP version from PHP 5.6.36 to PHP 7.2, but I have a problem when I want to use the migrate function of Session component.

My simple line of code :
$this->request->getSession()->migrate(true, $newLifetime);

The error returned :
Warning: ini_set(): A session is active. You cannot change the session module's ini settings at this time

I have already a session opened before by my login page, but I want to change the session life time on login.
My Symfony version 2.8.44
Thanks for your help
