Use the following information as a guide for how to migrate data from a Windows 2000 or Windows Server 2003-based host system.
You can migrate data from Windows 2000-based host systems into an storage unit by mirroring the data and splitting the mirrors (similar to the method described for UNIX systems). Create a full backup of the data before attempting any data migration. Migrating data maintains file ownership, permissions, and the date and time while the copy is made. The drag-and-drop function and the xcopy command might cause ownership problems to date-related information in the copy of the new data.
Mirroring the data and splitting the mirrors requires some outage to rename drive letters at the end of the migration. If the mirroring tool that the operating system supplies cannot be used (for example, if drive sizes in the old and new systems are not the same), you might be able to use a third-party mirroring tool to accomplish the same goal. If an outage occurs, you can copy Windows 2000 data to the new disk using the scopy command.
