Adjusting the software version is new to me...but, apart from the cycle setup, it is always possible to install a newer/older version..
If you read it somewhere please let us know where you read it. I am happy to learn something new today smile.gif
However the TNCs are all downward compatible, but when you get problems with newer software versions then you should take a close look at the programs and the error messages... although programs from newer software versions don’t always run on older ones..logically
