Acquiring company, the IMF, is buying a division of the Syndicate. Your mission, should you choose to accept it, is to plan out all of the technical aspects of an Active Directory migration and be ready for execution beginning Day One.

No one without a need-to-know in either company can know about this until the acquisition is announced publicly. You’ll be required to set up directory synchronization with the acquired entity but will not be able to establish a trust, because you won’t be permitted that level of access. Many of the sAMAccountNames in the Syndicate environment have different names than those in the IMF environment. There are 5,000 workstations that will need to be migrated – many of which are operated by remote workers who typically only access the corporate network via VPN. All of the technical back-end work must be ready in advance of the migration. You have three weeks to develop your plan and three weeks to perform the migration.

As always, should you, or any member of your migration team fail, you will be disavowed by the CIO. This message will self-destruct in five seconds. Good luck…

So, would you sign the NDA for this fictitious business situation and accept the assignment?

When Sunshine Children’s Home of Maumee, Ohio decided to transition from Exchange 2003 to Exchange 2010, they selected Binary Tree’s E2E Complete solution. The entire migration of 788 users was accomplished after-hours, in just one weekend—without disruptions to their current workflow.


Sounds pretty easy, right?

The Migration Impact of Office 365’s Max Message Size Increase from 25MB to 150MB

A lot of customers that I speak with on a daily basis are looking to migrate to Office 365 from a third-party hosting provider. In these types of environments, the hosting provider typically does not provide the rights required to migrate to Office 365 with the New-MoveRequest PowerShell cmdlet. This means that EWS or MAPI are often used as the transport mechanism to copy user mailbox data from the source hosted environment to Office 365.

The problem with this ‘copy’ based migration method is that the largest email message that could be moved into Exchange Online was 25MB. If you tried to move items larger than 25MB into Office 365 those messages would be rejected. As you can imagine – it is not hard to find users that have attachments in their mailbox that are larger than 25MB! Think about all those large PowerPoint slide decks, spreadsheets and videos that you have in “your” mailbox today!


But there is good news…

Active Directory (AD) is a critical cornerstone of your IT infrastructure. Therefore, any effort to migrate the AD environment must be planned very carefully in order to reduce risk and manage complexity.

This post will introduce you to a holistic, four-phase approach to performing an AD migration. It is not a project plan. We aim to give you guidance on what truly matters when creating the plan and selecting appropriate technology that will ensure a smooth transition.
