Some of our clients are wondering why we post updates of Ispirer tools every month. The answer is simple. Since the market is changing rapidly, improving our products is an endless process, as we should keep up with modern trends. Despite the fact that our products ensure high conversion speeds and quality migration, we still continue improving Ispirer products to stay unrivaled.
SQLWays Wizard was considerably changed in March. First, the tool now includes a pre-conversion feature that allows you to see how selected objects will be converted by SQLWays Wizard. Second, data conversion in multi-process mode for Microsoft SQL Server to PostgreSQL directions has been enhanced to provide a higher quality and conversion speed. Third, SQLWays Toolkit provides better support for Sybase IQ as a source technology.
NglFLy Wizard, a tool for automated application conversion, now has improved reports that contain useful tips about resolving possible conversion issues. Furthermore, the summary page has been expanded to give a more comprehensive overview about the conversion settings.
The Ispirer engineers updated Assessment Wizard as well. We improved the service estimation algorithm to collect info about a source database as quickly as possible.
What is more, the parser technology in Ispirer Toolkit has been extended for the following source directions: COBOL, PostgreSQL, Oracle, Informix 4GL, Firebird, Microsoft SQL Server.
