I am currently working on a project that I would like to migrate over to RichFaces 4 from version 3.3.3.Final. I was wondering...
is there anything major I should think about or know or think about before migration?
(might be a silly question but...) can you "mix" richfaces 3 with richfaces 4?
One of the main reasons I wanted to make the switch is to use richfaces 4 autocomplete, is there a way to do something like this useing richfaces 3 or would migrating over be the easiest?
I am using JSF.

Their recommendation is to follow their own RichFaces 3.3.x - 4.x Migration Guide — which appears to be far from complete, see EJP's answer here for the real experience.

No, you can't. It would conflict with itself.
