For larger migrations to Office 365 from any platform (Domino, GroupWise, Exchange on-premise) it is recommended that you engage your local Microsoft Team to run through a Microsoft Readiness Check.
There is an automated tool “on ramp for Office 365” available, that will provide some information on prep work required for your environment. However, by engaging Microsoft you are able to ask them questions and get recommendations on how best to prepare for your migration to Office 365.
Typically, we get involved with Office 365 migration projects at the time the Microsoft Readiness Review has been completed. We will review the report and provide our recommendations on an action plan. Usually there are decisions that need to be made that can potentially impact your environment. An example would be aligning your UPN field in AD for user accounts to your primary SMTP domain name.
Preparation is key for any email migration project, and Office 365 is no exception. If you need consulting assistance for your Office 365 project, then please Contact Us today. When you deal with us you deal direct with a messaging consultant.
