Hello everyone , I have a doubt and I need help. 
I am  working  in acquisition equipment  of tension and current in an electric system.   
This equipment uses LabView and acquisition board NI PCI-6220. I likes to know if it is possible to modify  the acquistion board, PCI-6220 to a NI USB 6210, whitout modify many blocks or all acquisition blocks?   
If  it is possible, is very difficult? And how it is done? 
thanks in advance
