FAQ
1. Will there be any data loss during the migration?
Absolutely not. I prioritize data integrity above all else. I perform rigorous row-count validations and checksum comparisons between the source Oracle database and the target PostgreSQL instance. We do not finalize the migration until every single record—including those in your 20M+ row tables—is a
2. How do you handle Oracle-specific features like Triggers and Stored Procedures?
While basic schema conversion can be automated, I manually review and rewrite complex PL/SQL (Oracle) into PL/pgSQL (Postgres). My experience with 400+ tables allows me to identify and fix proprietary functions that automated tools often miss, ensuring your logic remains intact.
3. Can you handle migrations for very large tables (20M+ rows)?
Yes. Handling "Big Data" tables is one of my specialties. I use high-performance data streaming and parallel loading techniques (such as using ora2pg or custom ETL scripts) to move large volumes of data efficiently without crashing the system or exceeding your maintenance window.
4. How much downtime should I expect?
Downtime depends on the size of your database and your network speed. During our initial Migration Audit (Basic Package), I will evaluate your architecture and provide a strategy to minimize downtime, such as performing an initial bulk load followed by a final delta sync.
5. What do you need from me to get started?
To begin, I typically need a schema export (DDL) of your Oracle database and a brief overview of your environment. For the actual migration, I will need secure access to your source and target servers. I am happy to sign an NDA to ensure your data remains confidential.
