Ispirer Tools Improvements, March 2023

March 9, 2023

Conversion is a multi-stage, intricate, and time-consuming process. Sometimes database or application migration projects can take months. For this reason, we regularly analyze every “cog” of our Ispirer Toolkit so that customers can get the most out of the automated process.

Each of our updates includes dozens of GUI improvements, hundreds of added conversion rules. As a result of all of our efforts, we are able to offer customers top-notch, user-friendly software that saves them time and money.

This time we have majorly updated our SQLWays Wizard. First, Ispirer experts improved progress bar logic. Now it is dynamic and shows information based on conversion stages of an object. Second, data migration from Informix to PostgreSQL is now multithreaded which speeds up data migration considerably. Third, our team created a preliminary conversion of a selected object on the DDL option page. Such a feature gives users an opportunity to find out how it will be converted. SQLWays Wizard update makes it possible to extract data from Oracle database using SCN which simplifies the process of selecting files.

What is more, our experts extended the assessment process to collect detailed information about the SQL statements and structures from the DB2 database.
