Migration Overview

Database Migration

Ispirer Toolkit automates the migration of database objects from Teradata to Vertica. Both conversion with connection to the source database, as well as conversion of files containing scripts are possible. Ispirer Toolkit supports migration of the following objects: tables, views, functions, procedures, sequences. As a result, each separate database object is converted to its equivalent in Vertica.

If you have your own applications, the Embedded SQL and Database APIs can be converted using either Ispirer Toolkit or Ispirer Service. As a result, they will be able to work with your new Vertica database.

Table and Data Conversion
Ispirer Toolkit converts tables with all related objects (indexes, referential integrity constraints) and data to the target Vertica database. All Teradata native data types are converted to the Vertica equivalent. If necessary, the user can change the default settings of data type mapping.

Procedure and Function Conversion
Teradata user procedures and functions are converted to UDxs in Java, which are used to deploy Vertica UDF. Each UDx type consists of two classes (one is nested in another). The nested class is the main one, it extends the ScalarFunction class and does the primary work (transformation, aggregation, etc.). The class usually has one method in which the actual work of the source function or procedure is performed. This class is named as the source procedure or function with the appended Factory. The second class is a singleton factory, it extends the ScalarFunctionFactory class. It defines one method that creates instances of the first class, and can define another method to manage parameters. It is named as the source function or procedure. Finally, Java UDx can be deployed to Vertica in the standard way.

Teradata built-in functions and procedures are converted to their equivalents in Java. If there are none, the tool converts them to the methods in a helper class in Java that emulate the same behavior, as well as work just like in the Teradata database.
