What is SQL Postgres migration?

SQL Postgres migration refers to the process of moving databases, data, and schema from another database management system (like MySQL, Oracle, or SQL Server) or an older PostgreSQL version to a new PostgreSQL environment. This process involves extracting the data, transforming it as needed, and loading it into PostgreSQL, often using tools or scripts to handle compatibility and data integrity issues. Proper migration ensures that applications continue to function smoothly with the new database and that all data remains accurate and accessible. Planning, testing, and validating the migration are critical steps for a successful transition.
