What you get with this Offer
I will migrate your MySQL database to PostgreSQL — covering schema conversion (data type mapping, AUTO_INCREMENT to SEQUENCE, MySQL-specific syntax to PostgreSQL equivalents), stored routine conversion (MySQL PL/SQL to PL/pgSQL), data migration with full validation, application query compatibility testing, and post-migration performance validation. MySQL to PostgreSQL migrations fail most commonly on implicit type casting differences, GROUP BY strict mode enforcement, NULL handling in boolean contexts, and stored procedure language differences that pgLoader or automated tools partially address but cannot completely resolve.
The migration covers schema conversion DDL, data type mapping (TINYINT(1) to BOOLEAN, TEXT to appropriate VARCHAR/TEXT, DATETIME to TIMESTAMP WITH TIME ZONE), sequence creation for all AUTO_INCREMENT columns, stored procedure conversion to PL/pgSQL, data migration using pgLoader or custom Python scripts, record count and key field validation, and application query review for MySQL-specific syntax incompatibilities.
Designed for development teams and organisations migrating from MySQL to PostgreSQL for its superior standards compliance, advanced features, or licensing cost advantages.
