By now you should have a relatively defined plan on what integration services you want to leverage from Microsoft Office 365, along with how you plan to scale out these services. Our next objective is to start preparing our environment for the integration services. In this chapter we will focus on working through the various core services available to Office 365 and their integration requirements for your environment. We will assume you have an existing Exchange Organization within your environment, consisting of Exchange 2010, or you are planning to add Exchange 2010 for this effort. We will focus on the following areas:
Preparing your Office 365 subscription
Active Directory preparation and readiness check
Basic infrastructure preparation
Defining the migration process
