Database Migration Services

PES migrates relational (Oracle, SQL Server, PostgreSQL, MySQL) and NoSQL (MongoDB) databases to cloud platforms — AWS, Oracle OCI, and Microsoft Azure. Zero-downtime migrations are achieved through Oracle Data Guard, GoldenGate, log shipping, and native replication tools.

Note: The migration strategies are recommendations based on database vendor and cloud provider best practices. Every plan is tailored to your database versions, data volumes, and compliance needs.

Supported Migrations

Relational Databases — Oracle, SQL Server, PostgreSQL, MySQL to AWS RDS, OCI, or Azure SQL
NoSQL Databases — MongoDB to MongoDB Atlas on AWS, Azure, or OCI
Zero Downtime — Based on requirements and available resources; using replication and cutover strategies
