I have not tried that in LV 8.+ yet so I will speculate.
Since NI is pretty good about making sure old stuff still works, I suspect you should be OK.
If not, you will have to explicitly specify the applicaiton instance they run in.
For all of these types a questions, I stongly urge you "Build early, build often" just to make sure you do not get blind-sided when the dead-line approaches.
