Your question implies that having a background in LabVIEW makes a difference. It doesn't.
Graphical vs. text, procedural vs. dataflow, inherently single-threaded vs. inherently parallel...you will basically have to forget everything about LabVIEW anyway, so don't worry about how C++ relates to it.
Go to the recent "C++ Noob" thread for advice on learning C++. But if you know LabVIEW and nobody on the team knows C++, why switch?
