MSSQL-to-PostgreSQL is a tool designed to facilitate the transfer of databases from SQL Server and Azure SQL to PostgreSQL, whether on-premises or in a cloud environment. Its efficiency stems from its optimized algorithms for reading and writing data, achieving speeds exceeding 10 MB per second on a typical modern system. Additionally, the inclusion of command line support enhances the automation of the migration process, making it more streamlined for users. This added functionality ensures that database administrators can perform migrations with minimal manual intervention, saving both time and effort.
