Berlin, 21.11.2025 (PresseBox) - Berlin, Germany – KeepTool has published a new technical guide describing how to migrate Oracle Databases to PostgreSQL in a structured, transparent way. The guide is based on numerous real-world migration projects and provides a practical workflow for developers and DBAs.

The full article is available here:
https://keeptool.com/...

Typical migration tasks include:
- Creating PostgreSQL-compatible table structures
- Rewriting views using ANSI SQL
- Copying data via PostgreSQL-safe INSERT scripts
- Transforming trigger logic into PL/pgSQL
- Converting Oracle SQL queries to PostgreSQL syntax

KeepTool streamlines these processes without hiding logic behind a "black box". Flagged objects, cleanly ordered DDL output, SQL rewriting tools, and PostgreSQL-compatible INSERT scripting give users full control throughout the migration.

The guide also discusses common challenges and explains how to prepare PL/SQL logic for PL/pgSQL. A follow-up article will cover the transformation of PL/SQL procedures, functions, and packages into PL/pgSQL.
