IMO, it is difficult. Their is no quantifying study for transition
complexities. How will you account for problems during flag days?
It is not the problem for MPLS transition alone. Many of our hard 
earned research are left unused because of transition problems.
The disruptive technologies like active networking and  overlay based 
solutions are not currently in use, as their is no effective method
for transition. A large scale test bed initiatives like planet lab 
will help in making such transition a reality. But, co-operation from
ISPs is necessary for making such initiatives into success. 
So, transition is more of research and  operational work rather 
than an IETF effort.
