When contracted, all migration and upgrade services are performed by the Teradata Services team.
This document focuses only on migrating an entire system, including access rights. To perform a full system migration, two archive operations must be performed, DBC All followed by DBC Only. The restores must be in the sequence of DBC Only, SYSLIB, DBC All, TD_SERVER.
Migrations are only supported from two major releases back. The minimum version for migrating directly to Advanced SQL Engine 17.00 is Advanced SQL Engine 15.0. Migration from releases prior to 15.0 require an intermediate migration to a supported release.
