Firmware 7.1.3 vs 8.1.3 vs 10.0.2

[rwolters]

Hello All,

I've had a D400 for about the last 18 months and have used several of the firmware updates in that timeframe. However, I've never tried to go back and use an earlier version. I would like to give 7.1.3 a try though. If I do that, do I just use the currently available online Configurator, or is an earlier Configurator required too?

Thanks for your help here.
