If you are planning to migrate from Windows NT4/2000/2003 or Novell to Windows Server 2008, Technology First use a tried and tested phased approach of workshop, scope/audit, test, implementation, review and support.
There are two ways to illustrate Technology First's approach to migrating from Windows NT4 to Windows 2008:
Domain Upgrade - A domain upgrade is the process of upgrading the Primary Domain Controller (PDC) and the Backup Domain Controller (BDC) of a Windows NT domain from Windows NT Server to Windows 2008
Domain Restructure/Consolidation - A domain restructure is a complete redesign of the domain structure, usually resulting in fewer, larger domains. This choice is for those who are dissatisfied with their current domain structure or who feel that they cannot manage an upgrade without serious impact to their production environment.
Some organisations might upgrade first and then restructure, while others might restructure from the start. Technology First can advise you on which route is the most appropriate for your business and plan its implementation. A recovery plan will also be put in place to prevent accidental data loss during upgrade, which will be the procedure of how to back up your domain controllers, applications, and other data. The recovery plan will determine if there is a point at which incremental migration can stop and full migration can begin.
