I had the luxury that as we deployed IPv6 across the network
we rolled it from the 6bone -> core -> edge over a period of a few months.
As we shut down the 6bone/3ffe stuff and moved people to gre/ip
and native the core was ready. This doesn't mean the edges have IPv6
turned on, but it's usually the flip of a switch.
Where possible take your core and IPv6 enable it and then
touch the upstreams at the same time/next time you do work there.
Assuming you patch devices for the various SIRT/PSIRT type
events, most devices will be rebooted once every 6-12 months. this
gives you the chance to drop in and enable ipv6 during or after that
change/maint window.
Rolling out the core really isn't hard, go ahead and do it. There
are plenty of people here who will help you with these steps.
