Ispirer Ecosystem for automated migration
Ispirer Toolkit is a solution for automated heterogeneous database migration. Using it, you can transfer tables and data, 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 code structures that do not have equivalents in a target technology.

Migration details overview
-
Ispirer Toolkit automates
![Ispirer Toolkit automates icon]()
Ispirer Toolkit automates the entire migration of database objects from SQL Server to PostgreSQL
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 and user-defined types. As a result, 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. They will be able to work with your new PostgreSQL database.
-
Table and Data Conversion
![Table and Data Conversion icon]()
Ispirer Toolkit converts tables with all related objects
Indexes, referential integrity constraints, and data are migrated to the target PostgreSQL database. All SQL Server native data types are converted to the PostgreSQL equivalents.
If necessary, the user can change the default settings of data type mapping.
-
Procedure, Function and Trigger Conversion
![SQL objects icon]()
SQL objects
Transact-SQL user procedures and functions are converted to stored procedures and functions written in PostgreSQL syntax, depending on the version of the target database.
![Triggers icon]()
Ispirer Toolkit automatically migrates SQL Server triggers to the trigger function, and the trigger itself to the PostgreSQL database
SQL Server trigger logic is moved to the trigger function as well. The tool then generates a trigger that calls this trigger function.
-
Built-in Functions and Procedures Conversion
![Built-in Functions and Procedures icon]()
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.
-
Working with User-Defined Types
![User-Defined Types icon]()
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
![Alias Conversion icon]()
Ispirer SQL Server to PostgreSQL converter replaces synonyms to the original object names
Moreover, if the SQL Server database has synonyms only for tables, Ispirer Toolkit can convert them to views by setting the appropriate option.
