Hi clruwe,
You will get converted iLok licenses for every eLicenser-protected permanent license that's on your account.
So, technically, you will have 2 licenses. And yes, you can run the corresponding products in 2 environments.
Bear in mind that our that there will be no new products or software updates for eLicenser-protected products once we have made the transition to iLok, but of course existing systems will continue to work.
EDIT: As mentioned before in this thread, the following products will NOT be available on iLok: Vienna Ensemble Pro 3/4/5/6, Numerical Sound FORTI/SERTI and ISP:IR (discontinued in 2014).
Best,
Paul
