Hello Pete - because of the different OS levels you will be unable to get most current on systems backlevel beyond OS 7.2 for both products. Here are the cut off levels for each product on their respective OS - you can get these updates from the Downloads/Archived Downloads on the portal.
OS Product Level
5.4 Con 5M30
5.4 Net 11M18
6.1 Con 6M09
6.1 Net 11M28
7.1 Con 6M12
7.1 Net 11M30
You can get most current shipping products for OS 7.2 - 7.4 directly from the downloads on that portal. For Console you can directly update to R7 from R6. If you are at R5 and can go to R7 you must convert to R6 first and then to R7.
And with Robot Network the host must be at a higher release then any of the nodes. So if your host can not be updated to most current your nodes must stay at the same Release and Mod level or lower then the host is at.
Both products will require new GUI installs as well
Please let me know if you have further questions
