First, it's best not to approach this as switching to IPv6. Think of  
it, instead,
for now, as adding IPv6 capability to as much of your IPv4 environment
as possible.

I don't know of any applications which are negatively impacted by having
IPv6 capabilities.  Several end-user applications do not play well if  
you
remove their IPv4 capabilities, although that is getting fixed for the  
most
popular internet-oriented ones fairly quickly.

The most important things to get on dual stack initially all play well.
These would include your internet-facing services such as your
mail gateway, web servers, etc.

If you can get 50 people or more in the room, I'd be happy to come
present to your group.  Hurricane Electric will pay my travel.
