All migrations are performed under the guidance of Teradata Customer Services.
Many methods and options are available to move data from one system to another. This document focuses only on migrating an entire system, including access rights. To perform this type of migration, you must first archive database DBC followed by all user databases and objects from the source system, and then restore these items in the same order on the destination system after initializing it using the sysinit command.
For migrations from Linux systems running Teradata Database releases earlier than 14.10 or from non-Linux systems, you must use the Teradata Archive/Recovery (ARC) utility in conjunction with Teradata Backup, Archive, and Restore (BAR) application software for archival and restoration. Starting with Teradata Database release 14.10, you can use the Teradata Data Stream Archive (DSA) or the ARC utility.
