Customer questions relating to Exchange resource forests are becoming more and more common for our technical team. Organizations want to consolidate their existing Exchange environments to a single Active Directory (AD) forest running Exchange 2010
, while leaving their user accounts in their old AD domains.

Merging multiple AD forests into a single forest is a VERY
complex undertaking, which requires transitioning workstations, laptops, servers, printers and all applications that interact within that AD environment. So it’s no wonder that customers shy away from that migration project
and go with a brand new build-out of an Exchange resource forest to run their messaging environment in a more centralized, consolidated infrastructure.
This may become an even more common method to deploy Exchange 2013
when it is released. However, there are some serious challenges related to linking active user accounts from one AD environment to a separate Exchange AD forest and successfully migrating all the email data intact.
In this article, I’m going to discuss the different steps that MUST be performed to do this manually and describe how our E2E Complete software automates this entire process.
There’s no getting around the need for Cross-Forest, or Inter-Org, email migrations
. They just happen. And in some cases an IT group has only a few days to plan out the transition. They are brought about by different events such as mergers & acquisitions, company divestitures, or just plain company partnerships when organizations want to combine their email environments onto a single platform. Whatever the reason for your migration project, you will need to address the same issues every time.
The cross-forest migration
process is quite complex and the Binary Tree E2E Complete
product can assist you to simplify and streamline the mailbox migration process. However, to begin with, you will need to synchronize the Active Directory (AD) forests, establish bi-directional data flow between the domains, and prepare the environment for the mailbox migration process.
What options are available? Are there solutions which can ensure the success of the AD transition?
