DAQmx Switch VI have red X

[vikasg]

I opened my old vi (2012/2013) in Labview 2015, all the DAQmx Switch palettes have a big Red X on the VI's. 

as shown here:

Is this something that has changed in Labview 2015? 

Is there a way to migrate the old files to the latest version?

Is there a specific popup if you try to open the VIs?

A solution may be to replace them with the appropriate VIs from your palette.

If I double click on any of those VI, the sub VI opens up and I do not see any errors within those subVI from what I can tell.

Here is a screen shot of the block diagram of  "DAQmx Switch Set Topology and Reset.vi"

I don't have the physical hardware to check if the VI is still functional.

If the VI opens and doesn't have a broken arrow, I think it might run okay... It may just be a discontinued version and the X is just telling you to replace it if you can.
