Note that it is unlikely to be simultaneous - I expect an overlap period of many 
months, if not years, between when the NBN is deployed, and when all the services have 
been methodically migrated according to a project-plan across from the copper to the 
NBN so that the plug can be pulled on the active equipment driving the lines inside 
the exchange.

for a reasonable treatment of the likely complexities of the migration process.
