Considering scenario of 70 domains with ard 1000 users per domain, my only conern was ,maintaining transport maps would be more of a manual task. I agree to fact of generating a backstacker but this process of migration will last for period of max 2 days or so which should be fine. Having said that i presume there is no better solution for split-domain scenario apart from maintaining user based transport maps?
