[CentOS] transition to ip6

I imagine some day in the near future there will be a switch to ipv6.
I cannot imagine ever remembering the ip address then...crazy.

My question, since i have never done ip6 stuff, is what does that mean 
on my webservers?

Would I just need to replace my ip4 with ip6 in my eths, bonds, bridges, 
and configuration files...and copy out my iptables to ip6tables, and 
change the dns servers?

all that does not sound to harsh.

anything especially daunting to make that switch (save from someone 
having to do that on 100 computers really fast!!)
