Ispirer Toolkit for Automated Migration

Ispirer Toolkit is a robust solution for automated heterogeneous database migration and application conversion. Using this tool, you can transfer not only tables and data, but also stored procedures, functions, packages, views, and triggers. This solution is based on an intelligent proprietary algorithm that analyzes data types, relationships between objects, reserved words, and even code structures that do not have equivalents in a target technology.

Ispirer Toolkit supports both legacy and most popular RDBMS, such as Informix, Sybase, DB2, Teradata, Firebird, Progress, Oracle, Microsoft SQL Server, PostgreSQL, MySQL. To ensure a smooth migration process, our support experts are available to assist with tool configuration or resolve any issues in a timely manner.

High quality SQL code conversion

Expert system with 20.000+ conversion rules and 100.000+ automated tests.

Flexibility

Nimble configuration with 300+ parameters and options for SQL objects and data multithread migration.

Free smart assessment

Ispirer's free Assessment Wizard for migration scope and complexity evaluation.

Comprehensive migration analysis

Intuitive and instructive reports for cost-effective post-migration polishing.

Ispirer Toolkit is a comprehensive solution for database migration. The core of the tool is designed to handle any type of migration regardless of the location of the target database. The tool facilitates the database migration to both on-premises and cloud environments. Ispirer Toolkit effortlessly integrates with popular cloud services including Google Cloud SQL, AWS RDS and Azure Database.

Migration Overview

Ispirer Toolkit is a comprehensive migration solution that helps to convert SQL Server to PostgreSQL automatically. Both conversion with connection to the source database, as well as conversion of files containing Transact-SQL scripts are possible. The first option is most recommended, as the tool will get all the required information about object dependences directly from the database. Ispirer Toolkit can migrate the following objects: tables and data, views, functions, procedures, triggers, sequences, user-defined types. As a result of conversion, each separate database object is converted to its equivalent in PostgreSQL.

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 PostgreSQL database.

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

Procedure and Function Conversion
SQL Server user procedures and functions are converted to stored procedures and functions, written in PostgreSQL syntax, depending on the version of the target database. Transact-SQL built-in functions and procedures are converted to their equivalents in PostgreSQL. If there is none, the tool will try to convert the functions to PL/PgSQL expressions. They will emulate the same behavior or generate a user-defined function that will work the same way as in the SQL Server database.

Trigger Conversion
Ispirer Toolkit automatically migrates SQL Server triggers to the trigger function, and the trigger itself to the PostgreSQL database. Microsoft SQL trigger logic is moved to the trigger function as well. The tool then generates a trigger that calls this trigger function.

Working with User-Defined Types
Ispirer Toolkit supports conversion of user-defined type to its equivalent in the PostgreSQL database. According to the type and its usage, it may be converted to a user, native type, or to a PostgreSQL table. Then a set of user-defined functions is generated. This allows to work with values in such tables.

Alias Conversion
Ispirer SQL Server to PostgreSQL converter replaces synonyms to the original object names in places, where they are used in SQL Server. This is the default behavior of the tool. Moreover, if the SQL Server database has synonyms only for tables, Ispirer Toolkit can convert them to views by setting the appropriate option.

Migrating data from SQL Server to PostgreSQL involves transferring table structures and their columns while adapting to PostgreSQL’s open-source syntax. You’ll need to create compatible schemas, as some data types and functions differ between the two systems. Since PostgreSQL is a powerful source-available database, it offers strong alternatives to SQL Server’s proprietary features, ensuring a smooth transition for queries, constraints, and stored procedures. Properly mapping and transferring data from SQL Server using SQLWays ensures accuracy and performance in the new environment.

Migrate Logic From Database to Application

Ispirer has a solution to unlock the full potential of your database. Storing business logic in your database can sometimes impede performance, but Ispirer Toolkit can help you migrate this logic to an application layer seamlessly.

Automated conversion of SQL objects to application code. Ispirer Toolkit supports Oracle, SQL Server, Sybase, PostgreSQL, Java, C#, Python, etc.
In case of changing the RDBMS, Embedded SQL will be automatically rewritten to adhere to the syntax of the new database.
Migration with\without connection to databases. Ispirer Toolkit can work with or without a database connection. Both options allow you to successfully migrate business logic from the database to the application layer. However, it is worth considering that connecting to the database allows Ispirer Toolkit to take into account additional data from the database and helps improve conversion.

In addition to PostgreSQL, Ispirer can offer you migration from Microsoft SQL Server to other databases, including:
