Can anyone advise please.

As most people may be aware BT are planning to roll out IPV6 by the end of 2016 and pondering switching on IPV6 internally in anticipation

I'm currently using a 2850 using 3.6.6.1

Has anyone done this? Have you got any advise? Is it as simple as switching it on? I have IPv6 capable switches and my printers are all IPv6 capable (I think)..

All advise appreciated.
