Can I directly Upgrade Laravel 5.5 to Laravel 6?

I need to upgrade my website from Laravel 5.5 to Laravel 6.

Can I directly upgrade to it?

Laravel 5.5 => Laravel 6.x

Or

Do I need to upgrade step by step?

Laravel 5.5 => Laravel 5.6 => Laravel 5.7 => Laravel 5.8 => Laravel 6.x

Or

Let me know any other optimum way.

Thanks in advance.
