Migration issues with BPOS transition

Hello,
I am sure you are aware that migration from BPOS will commence three to four months after GA release. Majority of us are in the beta which expire in about a month so I am wondering whether Cloud partners with BPOS be migrated earlier in order for us to be able to continue testing and demonstrating O365 to our customers?
I would be grateful if someone can please give me an answer to this concern?
