Is it possible to run a LabWindows/CVI RT application written for PXI on a cRIO-9081?

I have a CVI Real Time application running on a PXI with Pharlap.  I have one cDAQ chassis nearby, and one that is around 10m away.  We have been using a USB extender, but we get faults with the remote DAQ from time to time.  I thought I would be slick and replace the cDAQ with a cRIO.  The PXI would send DAQ task configurations to the cRIO and the cRIO would build the tasks and serve the data back to the PXI over TCP/IP.  

I am trying to provision the cRIO, but I don't recognize many of the software options and I don't have the others I expect like DAQmx.  When I installed NI CompactRIO I did not select drivers because I didn't want it to change the driver version that I am stuck on which is 18.6 for the PXI.  The oldest option I had for the RIO was 19.0.  This RIO has Pharlap.  Can it not be treated like a PXI with Pharlap?

Put CVI RT aside, cRIO-9018 running Pharlap cannot control a cDAQ. Only cRIO-9081 running Windows or cRIO-904x/5x can control a cDAQ chassis.

I don't need to control a cDAQ with the cRIO.  The cRIO already has 8 slots to replace the 8 slots that the cDAQ had.  The cDAQ goes away.  I just need to be able to run LabWindows/CVI Real Time on the cRIO running Pharlap, and I would need DAQmx.

I installed NI-CompactRIO 19.5 on my development machine, but I deselected NI-DAQmx because I didn't want to change my drivers on the development PC from 18.6 which was the last drivers for PXI that work with CompactDAQ.

This is what Add/Remove Software looks like on a PXI:

This is what it looks like on the cRIO from the same development PC:

Note that there is no LabVIEW Real Time, LabWindows/CVI Run Time Engine, or DAQmx possible for the cRIO.  I assumed they would behave similarly since they are both running Pharlap.

Sorry I misunderstood your question but unfortunately only cRIO-904x/905x support DAQmx.

The other cRIO include cRIO-9081 only supports Scan Engine or FPGA Mode.

Thank you for confirming that.  I'll have to have my colleague program the RIO in LV.
