I recently delivered training on Dell’s Migration Manager, specifically targeting Microsoft Exchange and Active Directory, and I’d like to share some tips for a smooth migration. Any migration is no small task for IT, and those who have conducted a migration in the past often shy away from doing it again. That said, Microsoft Server 2003 Datacenter, Enterprise, and Standard Editions will go End of Support (EOS) in July 2015, and many enterprises are still running Microsoft Server 2003. Many of those servers house Active Directory, Domain Controllers, Exchange 2003 Servers, SQL Servers, and more. Those Exchange environments will need to move to a newer platform such as Microsoft Exchange Server 2013. As you know, Exchange and Active Directory are tightly integrated, and migrating both Exchange and Active Directory will be a big challenge for many in the coming months. Read on to find out what you can do to ease the transition. [read more]
The first step in any major project is preparation. Data migration is a very strategic project, and budgeting should be part of the initial planning which may include new hardware given that many Microsoft 2003 Servers are likely running on older hardware, and the importance of end of support cannot be ignored. Data center migrations are a complex and time consuming activity that must be executed without affecting business operations. A hardware refresh, software upgrade, or both, mean that SLAs including performance, availability, and data protection must be maintained.
A question I often hear is “How long does a migration take?” In smaller organizations, an offline migration may be accomplished over the weekend, but in many SMB and larger enterprises these projects will occur in phases over several months.
Microsoft Exchange Migration Challenges
There are several common challenges of a Microsoft Exchange migration. Knowing them ahead of time will allow you to better formulate a plan and manage your environment during the process. These challenges include:
- Understanding user and organization impact—Nail down how Exchange is used by the business and how possible downtime may affect it.
- Inadequate data protection—Back up your Exchange data and know how to recover it.
- Failure to plan for post migration—Be aware: there will be post migration tuning required. Build time for that into your plan.
- 32-bit applications running on Server 2003—If you’re migrating to a 64-bit architecture, you’ll need to upgrade or replace these legacy applications.
- Inconsistent or absence of a coexistence strategy—You won’t move it all overnight, so plan accordingly.
Microsoft Active Directory Challenges
Active Directory has its own migration challenges (aside from changing the DC, Schema Master, and the Global Catalog), especially where acquisitions may include multi-domains, one way trusts, and limited AD visibility by IT staff. This is no surprise to anyone who has been involved in previous migration projects.
- Multi-Forest, Multi-Domain, Trusts
- Privileged Accounts, AD Admin, Domain Admin, Schema Admin, and the associated tasks.
- Users, Computers, Groups, and Service accounts
- OU and GPO sprawl
- Native tools are not granular enough to help with migration
