Reality XP Flight Line T with Windows 2000?

I'm using my very highly customised FS2004 (with hardware panel etc.) with Windows 2000 Professional. It works well so I consider deinstalling my Windows 2000 Professional, installing Windows XP and then installing all my applications, extensions etc. very time consuming (I estimete reinstalling everything a 40+ hours work) and risky.So I'd like to know if anybody tried with any success Reaity XP Flight Line T (current version 5.2.1) with Windows 2000 Professional? This product requires Windows XP...Because I'm owner of RealAir SF260 I already know how much your simming experience in VC can be improved with gauges running smoothly (especially with TrackIR). The idea of adding Reality XP gauges to my other GA planes like Dreamfleet Cardinal sounds great. But the task of reinstalling my complete system only to upgrade to Win XP looks impossible to me
