grantedly I come from a SOHO (customer side) background, but I don't really 
see where the difficulty is.

What I normally do with networks that I switch to v6 is this:

0a) Leave IPv4 the hell alone! It works. Don't fix it. Don't even think 
about taking it away from the admins! They would eat you for lunch (or 
sooner).

0b) Don't plan for production use immediately. Plan for a transition phase 
of at least 6 months. This gives you time to explore your options.

1) switch v6 on (configure routers, there are easy HOWTOs)

2) add v6 to DNS and some other services (over time)

3) relax, your main job is done, most hosts will switch it on magically.

The actual work time for this is very little. And you'll have a working 
dual-stack environment afterwards. Now you can start to transition 
applications one by one over a longer period of time.

There are a couple of other things you can think about while the test and 
transition phases are still running - like unportable applications, address 
stability or renumbering after a provider switch, DHCP-PD, a final v6-only 
network in 2015 or maybe 2020, etc.

There is really no need to disrupt the network or the global addressing 
architecture just because someone wants to replicate the old v4 work 
instructions on a v6 network - there is time enough to explore and create 
new instructions while the network already works in test mode.
