How to change the resource of an old project from 7830r to 7841r for a NI FPGA module?

[Boning9]

Hello,

Could you please tell me what is the easiest way to change the target resource (the device
information) for the FPGA in a old project? We are using a 7841R board, but the
old LabVIEW project always treat the board as 7830R and I therefore can not complete the compiling and run
the project. 

Thanks!

You need to add the new board as a new target to the project. If you're using a recent version of LabVIEW you can then drag all the resources from the old FPGA target to the new one (I don't know if this works for IO items). In older versions of LabVIEW, you may be able to drag the files but you'll need to recreate the IO, FIFOs, memory blocks etc.

Is it possible to load the .lvproj file into notepad and do some manual editing of the entries to make it a 7841R?
