You can probably find this severely repeated if you Google 
hard enough, but it's not so much a "migration" as it is an 

v4 isn't going anywhere (for a while). v6 will live side-by-

Depletion will occur "toward" the LIR's, i.e., operators 
won't be able to receive any new allocations from the 
registries. However, these operators may still have some 
free v4 space to hand out to new Internet users for, 
perhaps, several months (depends on the rate of user demand 
- maybe, as a result of no more v4 space among some 
competing operators -, operator size, e.t.c.).

Guidelines to vendors come from us, the customers. We need 
to place the socio-economic pressure on our vendors to 
provide support for v6 in everything that we're currently 
doing with v4.

The IETF and other such standards bodies concerned with IP-
related protocols will continue to develop guidelines on how 
features should implement v6 (and how features should be 
implemented, period). However, as it is today, there are a 
number of v6-related RFC's and/or drafts that the vendors 
have not yet implemented, not least of which are for 
protocols already well-supported in v4. The pressure for 
them to do so has to come from us, the operators/users.
