If the code is recompiled, yes, it should work. There were a few changes to WPILib, such as the camera and compressor needing to have the control VI dropped in Vision or Periodic. Otherwise, I would expect the code to work.
Our code for last year worked without problems with the new LabVIEW and cRIO image. We moved the cRIO modules to where they are supposed to be. Since we used the default locations for the modules last year, we didn’t have to change anything in our Begin VI to correct module numbers as they updated themselves automatically.
