Alex, you can go from 0530 to 0710 - but you must do some level of conversion to ensure compatibility from UX to PC so that no illegal UX characters remain. there is a conversion tool to allow you to do this - it works very well.
0710 is a PC only revision and can be taken down to UX 0530 - but it might be that there are some changes you need to make - and for sure there are lots new features at 0710. The software is about 3 years further on. Any PC only features like VTEP will not be supported on UX either.

Just a heads up: The oti statement requirements for the UNIX controller and the pc can be different. So if you're using an rs-232 port in your testplan, you might need to change it.
