Migrate from ParticleManager to our new Particle System?

Is there a tuto to migrate from ParticleManager (used in 0.9) to our new Particle System ?

Is there any esay way to keep our code ? I worked a lot having an good render effect for dice explosion rendring a moving flame.

How can i not rewrite everything while  sing JME 0.10 ?

They're not very different I believe, except in that the new system also supports a lot more features.  Well, someone should be able to help you more than just this though…
