Migrating a lot of DAQmx Global Virtual Channels

[hfettig]

I have a project with 200+ DAQ global channels. I now have to migrate the system from SCXI over to PXIe. I would like to keep the same channels and just swap the physical channel in the virtual channel. This works fine in NI MAX one by one but I was wondering if it would be possible to do programmatically.

Maybe exporting the channels into a TXT file from NI MAX, then using RegEx or just a search and replace for each channel in LabVIEW, and re-importing them in NI MAX?

Let us know what works for you,

To the OP: I did something like this a long, long time ago and it worked out pretty well.  I did my search & replace with a text editor (probably Notepad++, maybe plain old Notepad) so I could see and confirm the changes.

For future reference: the *default* option for exporting a MAX config is a special (binary?) format with a ".nce" extension.  You need to manually choose one of the text-friendly formats.

As I recall, the .nce format is more comprehensive,  while the text format exported all the first-level stuff I cared about but not quite *everything*.  It was more than a decade ago though, so the text format may have gotten more comprehensive in the meantime.

Thank you for pointing me towards the ability to export in text format.

I used the export as INI format, used search and replace, and then imported everything again. Worked like a charm 🙂
