Performance of Lab Tests
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
In the lab test, match your test environment closely to your production network:
Use the same type of server in your test environment as in your real environment. If you will migrate users from an old domain to a new domain, include both the old and new types of servers in your test environment.
Run a test migration from at least one computer running each operating system from which you will migrate. For example, if you need to migrate user state from some computers running Microsoft® Windows® 98, some running the Microsoft® Windows NT® Workstation version 4.0 operating system, and some running the Microsoft® Windows® 2000 Professional operating system, test at least one computer running each operating system.
Make backups of the data residing on the computers from which you are migrating user state so that you can easily reproduce any problems that you encounter. If you adjust a custom script to solve a problem, it is hard to know whether the change solved the problem if you cannot reproduce the problem.
