TRANSFORMATION
• AD is the nexus for your application infrastructure
• Few directories are as visible and impact end users as much as AD
• Users’ AD identities are used to access resources
• AD identities are an inescapable part of corporate life
The Role of Active Directory in Your Environment
• Mergers, acquisitions and divestitures
• The desire to reduce complexity which in turn generates lower maintenance costs
• Some network topologies inhibit the adoption of new technologies (i.e. Office 365)

Defining the End-‐State of Your AD Infrastructure Analysis and Rationalization: Making the Right Decisions
• Windows Trust Requirements
• Windows Password Migration Requirements
• NetBIOS Naming Resolution Requirements
• DNS Naming Resolution Requirements
• Group Policy Requirements
Active Directory Domain Migration Checklist
• Migrations are usually gradual events
• Even small environments should plan for coexistence
• Neither the source nor target environment are likely to remain static during the migration
• Synchronization maintains transparent interoperability and minimizes risk, downtime and interruptions to users regardless of migration state
AD Synchronization versus AD Migration
• User Provisioning
• Group Management
• ACL Administration
• Password Synchronization
• Continued Reporting
On-‐Going Operations During An AD Migration Managing AD Environment During Coexistence
The End User Experience During an AD Migration
• This is where the rubber truly meets the road
• Migration must maintain:
• The user profile
• The drive mappings
• The Outlook connectivity
• User workstations need to stay connected (during the actual migration)
Maintaining User Functionality and Productivity
• Exchange is reliant on Active Directory
• The migration of a mailbox directly impacts the AD user experience and vice versa
• Any migration project must account for the relationship between AD and Exchange
The Relationship of AD Migrations with Messaging Migrations
• Exchange is wholly dependent upon AD for directory services
• Mailbox objects intersect AD identities
• A split Global Address List can make collaboration challenging
• A user’s Outlook profile is tied to their workstation profile
The Effect of AD Migrations on Messaging
• Replace remote office domain controllers
• Convert server local users and groups to domain accounts to simplify server management
• Consolidate legacy server to physical or virtual Windows severs for better performance and management
• Replace aging, failing, or unsupported legacy file servers
The Importance of Windows Server Migration The most overlooked aspect of Active Directory migration
• SIDs are not portable across member severs
• Access to files, folders and shares must be maintained during and after the migration process
• Changes must be synchronized during the migration process
• User's mapped drives must be maintained after the migration
