Top 5 Interforest Active Directory Migration Tips

Migrating between Microsoft's Windows Active Directory forests can be an intimidating project. This article provides 5 Active Directory migration tips that are bound to save IT pros time and aspirin.

1. Plan, plan, plan

Planning is the best way to a smooth Active Directory migration.

The most common error is a lack of planning. Don't horribly underestimate the impact … an AD migration. Research the impact thoroughly and properly develop migration plans.

At the end of a thorough evaluation, IT pros will know their AD requirements for structure, security, bandwidth, hardware and timeline. AD is not forgiving, so it's easier to get it right the first time than try to clean up afterward.

2. Ask for help

Going it alone is a sure-fire way to blow it. Try not to reinvent the wheel.

Not asking for help before starting the project is asking for trouble and results in the same mistakes our experts have seen – and solved – many times.

3. Ensure redundancy

A lack of server redundancy can be the costliest of AD blunders. Except for single-server environments, a minimum of two domain controllers should be installed for load-balancing and failover.

4. Enlist expert support

Recruit a migration expert, as needed, at the start of the migration project to avoid pit falls. Keep the migration expert available, as required, during the begining phases of the project to help guide the success of the project.

5. Use advanced Migration tools.

There are 3 major migration software tools on the market from Quest software, netIQ and Winzero technologies.

Test the tools in a lab, compare cost to benefit and choose the tool that can more easily meet the challenges and issues what will be faced during the migration process.
