Consequences of upgrading from 4.4.4 tethered to untethered?

Hi guys,

I’m happily running 4.4.4 tethered with the latest aTV Flash and have had a wonderful run since mid December without losing power.  But since the untethered J/B is out now I figured I might want to go the whole way.

I assume that when I JB with the latest Seas0nPass to untethered, the device will be completely wiped.  Is there any way I can preserve all of the configuration I’ve got currently set up on the device (even if I have to resort to ssh’ing into it), or do I have to reconfigure everything all over again from scratch?

Thanks for an amazing product!
