There are a number of administrator tasks you need to do to prepare for transition from BPOS to Microsoft Office 365 for enterprises. When transition happens, it will probably occur over a weekend, and may take a few days to complete. During the transition period, the Microsoft Online Services Administration Center is locked to prevent any issues with your transition. Your subscriptions are also locked in the Microsoft Online Services Customer Portal during transition. After transition, there are some tasks you need to do to complete your transition to Office 365.
To assist your users with their transition tasks, see Transition your user account from BPOS to Office 365.
We can also give you a hand because we know BPOS and Office 365. Our focus is small businesses run by women because we care about service and listening to your requests and questions.
Please call if you need a hand to prepare or would like some help with the products before during or after transition.
