Update Xbian Rpi2 to Rpi3 with xbian-config

[howdy]

Hi guys,

Im using xbian for a couple of months and im very happy, running also my Openhab stuff on it.
So, its getting time to test the new RPi3 with the config I have.

Newest 16.0 xbian installation.

I took my SD card with overclocking deactivated in xbian-config and test it with the Rpi3, works well!

So is it possible to update the Xbian environment to the new hardware seettings from the Pi 3 with xbian-config?
I use the preliminary setup with another SD card which is running fine with 1,2Ghz.
But then I ran in trouble to setup Java, openhab etc.
Burned some hours last night with that...

I'd like to avoid a new setup, because I took a lot of effort in installing java, openhab etc. stuff.

I'm happy to get some advice!
Cheers
