Google Cloud Migration Center vs Ispirer SQLWays

Google Cloud Migration Center helps plan moves from on-premises systems or other cloud environments to Google Cloud. It estimates future Google Cloud costs from existing resource sizes and configurations, and can inventory servers and Microsoft SQL Server, MySQL, and PostgreSQL databases. Assessments can report total cost of ownership, show application and network dependencies, and suggest destinations based on technical fit. Planning tools offer guidance on what to move and how, including rehost, replatform, and refactor strategies. Infrastructure information can be collected automatically once or continuously, or imported manually. Documented discovery covers AWS assets, Azure virtual machines in preview, and on-premises servers and virtual machines. A Linux and Windows discovery client can create offline reports without sending sensitive data to Google Cloud; the installed client itself runs only on Windows and does not discover databases. The service says it does not collect application or file-storage data. Estimates and assessments cost nothing, though other Google Cloud products may incur charges.

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.
