Frequently Asked Questions

No SQL knowledge is required. SCT has a point-and-click interface — you select your databases, click Compare, and the tool does the rest. Results are displayed in a clear, visual format.

Yes. SCT fully supports Azure SQL databases. You can compare on-premise SQL Server to Azure SQL, Azure SQL to Azure SQL, or any combination. The process is identical to comparing local databases.
