+# Teradata to Autonomous Data Warehouse on OCI Migration Guide
+
+Reviewed: 04.01.2024
+
+## Why move Teradata to Autonomous Data Warehouse on OCI?
+
+Legacy Data Warehouses, like Teradata, present a lot of inconveniences nowadays. The monolithic architecture implies high costs both in terms of hosting and management. Also, legacy Data Warehouses are difficult to scale (up/down, out/in) and require very skilled personnel to operate. The CAPEX model associated costs and the costs associated with this expert personnel, among others, are making the companies move the legacy database systems to the cloud rapidly. 
+
+On the other hand, the Scalability and Elasticity, inherent in OCI, allow companies to scale the databases up or down based on the business needs and changing workloads.
+
+Oracle Autonomous Data Warehouse (ADW) offers a flexible, scalable, highest-performing, highly available, and secure data warehouse solution that fulfills all these operational and cost challenges. Easy management and automation and built-in disaster recovery tools are other advantages that ADW provides.
+
+## Potential challenges & migration tool
+
+The process of migrating from Teradata to OCI Autonomous Databases (like Autonomous Data Warehouses - ADW) presents a number of challenges that users will have to deal with, like differences in the implementation of structures, objects, and data types, data extraction methods, data transformation requirements between the two platforms, data consistency and integrity, the final data loading, and more...
+
+SQL Developer can assist this process by using its built-in functionalities and tools. Using SQL Developer in a migration can help to reduce the efforts, accelerate the whole process, and reduce human errors.
+
+# When to use this asset?
+
+Once a decision has been taken to migrate a Teradata database to an Autonomous Data Warehouse on OCI, this step-by-step guide can help Data Engineers, Developers, and Oracle Database Administrators with the data migration process.
+
+# How to use this asset?
+
+A comprehensive guide to migrate a Teradata database to Autonomous Data Warehouse on OCI using SQL Developer is available in the "files" subfolder of this GitHub folder, named "Teradata to ADW Migration with SQL Developer_v1.1.pdf". Follow the steps to prepare for your Teradata to Autonomous Data Warehouse migration.
