If I upgrade PHPStorm license to IDEA Ultimate, will I still be able to use standalone PHPStorm?

There is an option to upgrade PHPStorm license to IDEA Ultimate and, as I understand, get the full functionality of PHPStorm in it.

But if, for whatever reason, I prefer to use actual PHPStorm, will I be able to continue using it? Or I'll have to fully switch to IDEA Ultimate?
