AWS Schema Conversion Tool vs Ispirer SQLWays

AWS Schema Conversion Tool (AWS SCT) converts database schemas between engines, including relational OLTP, data warehouse, and NoSQL schemas. If it cannot automate a conversion, it gives guidance for creating an equivalent schema in the target database. A project wizard estimates migration complexity for supported destinations and generates a report for comparing target options. For warehouse migrations to Amazon Redshift, it can manage data extraction agents; it can also create, run, and monitor AWS DMS endpoints and tasks. AWS SCT converts SQL embedded in C++, C#, Java, and other application code for users to review, edit, and save. Supported workload conversions include SSIS packages, Teradata workloads, and Apache Oozie workflows to specified AWS services. It is both a standalone, project-based application and a command-line tool. Planned converted schemas stay local until applied to the target. AWS SCT is free and supports 64-bit Microsoft Windows, Fedora Linux, and Ubuntu Linux. It also supports FIPS standards for connections to Amazon S3 or another AWS resource and is compliant with FedRAMP.

Ispirer SQLWays automates conversion between different database systems, including schema, data, tables, stored procedures, functions, triggers, and views. Migration options include data type mapping, migration queries, conversion reports, file output, object name mapping, dependency handling, and query testing. The product supports databases on Windows, Linux, or Unix, including on-premises and cloud environments, even when source and target operating systems differ. It connects to source databases through ODBC drivers and uses native utilities for target connections. Named cloud environments include Google Cloud Platform, Amazon Aurora, and Azure SQL DB. SQLWays can use a custom AI provider or local models; its built-in AI chat can help resolve errors, refactor code, and generate documentation. AI verification compares converted results with the source, fixes issues it finds, and flags complex structures for attention. Command line mode supports scripted, repeatable or phased migrations, including multithreaded work. Ispirer says SQLWays uses read-only privileges, does not modify the original system, and does not transfer data to third parties. A 14-day trial is available, limited to 2 GB, 20 database objects, and 1,500 measured lines of code. Listed licenses include Light at $395 a month for a 1-month license and Starter at $719 as a one-time purchase for a 3-month license.
