Not really. You can get some general things like bones maybe blendshapes to go over and thats it. Rest is going to stay n the other package.
if not, is there a way to get rigged/animated models transferred from
one package to another?
No if they would have the same features they wouldnt be 2 separate packages. Theres some things one can usually transfeer most will not go over no matter how much you would like to. Other then manually redoing the rig in the other system. Even then its possible that it wont work because the other system works diferently and might be missing osme parts of the toolset.
So you will be looking in remeaking everthing into max from scratch most likely.
