Legacy Particle System into new one

Hi,

I'm in charge of a project made in older versions of Unity, and I'm in charge of getting it to work on Unity 2018. All particles were using the Particle Emitter system, and it doesn't work with the newer versions.

Is there an easy way to change gameobjects with components like Ellipsoid Particle Emitter, Particle Animator and Particle Renderer into Particle System?

I there a tool for it? Or does anyone know how to do it manaually, if I have to?

Thanks!
