Do you have radars for the 'SW stability issues' you mention? Again, note that software will most likely have to change when moving to a J174 since its minimum OS is Mojave. I would really like to understand the need here. We can support it, but since J174 is not widely used yet, you may have more problems with it, than just fixing your software to run on J64 using the same OS you're running on J90.
