System compatibilty issues for upgrade from LabVIEW 5.0.1 to latest LabVIEW
I have inherited an old experimental set up running with Labview 5.0.1 on WindowsNT with NI acquisition hardware (see attached picture for details) and I want to upgrade to the latest LabVIEW version to run on WindowsXP. Before doing the upgrade I have a few questions:
- Will there be a compatibility issue between the hardware and the new software/environment ? (ie. will a hardware upgrade be necessary ?)
- Will any of the application G programming code that drives our experiment be re-usable or will a complete rewrite be needed ? I am a LabVIEW programming beginner and would very much prefer only a slight modification of our existing code 
- Alternatively I tried to run the application with LabVIEW 5.0.1 on WindowsXP and although all the hardware was recognised, the set up recorded some strange data: the voltage curve had the expected shape but wrong values. Any ideas what happened ? (both NIdaqmx and Traditional drivers were installed on this PC).
Many thanks for your help,
Nick

Hi Nick
On general basis I think you can transfer you design to Labview 8.x and run the code. But it is some obstacles on the road. First of all you can not read your old 5.0 code in 8.x. But the trick is to convert it to a newer version like say 7.0 or 7.1 Then you can read it Labview 8.x. You can post your code in this forum. Someone will help you with the conversion. I also guess your Daq board is not supported by the new DaqMX driver. So you may use an older daq driver. The same thing apply to the GPIB driver I think. You should call NI and ask them for advice regarding which driver to use.
Then you install Labview 8.x on the new computer do not install any Daq driver or GPIB driver. This because you can not replace driver with an older one. Then you install an older driver to a newer Labview system some files might get installed in the wrong folder. Read this to avoid this to happened http://digital.ni.com/public.nsf/allkb/F185E098C7EC5A3486256D2E00691BB2
Some GPIB issues
If your GPIB card is made for ISA buss, I think you have to get a new one. Modern computers do not have ISA buss. It is also possible that your old program is not made for VISA. But it should not be to hard to convert to VISA. Or you may take a look at and see if NI has a VISA driver for instrument.
Good Luck
