Command Prompt has managed source-to-PostgreSQL migrations across Oracle, MySQL, and SQL Server for organizations of all sizes and industries, from SMBs to global companies, including highly regulated FinTech and HealthTech sectors.

  
We plan for the hard parts, including schema conversion edge cases, stored procedure rewrites, application-layer compatibility, data validation at scale, long before the work begins, not during or after the process.  


## Your Migration, Done Right

Moving to PostgreSQL is one of the smartest infrastructure decisions you can make, but only if the migration itself doesn't become the problem.

  
Command Prompt brings both project management discipline and deep technical expertise to every engagement, so your transition stays on schedule and your team stays focused on what matters.

  
The result: lower licensing and support costs, a thriving open source ecosystem at your fingertips, and a database built to last.  
  


## Benefits of Migrating to PostgreSQL

  * Zero license fees
  * Reasonable support costs
  * Lower personnel costs
  * Proven adoption and growth of industry
  * Proven reliability and data integrity with true ACID compliance
  * Pure, Free, Open and BSD licensed
  * Active ecosystem and community
  * Zero vendor lock-in
  * Cloud friendly
  * Scalable and High Performance
  * The most standards compliant database
  * Extensible  




## Why Most Migrations Stall

Organizations that attempt Oracle-to-PostgreSQL migrations without a specialist tend to hit the same friction points:

  * Schema conversion is straightforward; stored procedure and trigger rewrites are not
  * Application code assumes Oracle-specific syntax and behavior
  * Testing at scale surfaces data integrity issues late in the process
  * Cutover planning underestimates downtime risk
  * Post-go-live performance is worse than expected because PostgreSQL tuning was an afterthought



We address all of these issues before they become blockers.  


## What the Migration Covers

### Assessment Phase

  * Review of business functionality, availability, and security requirements
  * Analysis of tables, stored procedures, triggers, including the number and complexity
  * Identification of syntax and functionality differences between source and PostgreSQL
  * Extension evaluation: what PostgreSQL extensions can replace source-DB functionality
  * Testing strategy design: data, code, and application correctness validation
  * Deployment options: on-premises, AWS, GCP, hybrid
  * Data conversion and synchronization planning: size, downtime tradeoffs, parallel operation
  * Skills and training gap identification for post-migration operations  




### Migration Execution

  * Schema conversion and stored procedure rewriting
  * Application-layer compatibility work
  * Data migration and validation
  * Cutover planning and execution support
  * Post-migration performance tuning and stabilization  




## What You Receive

At the end of the assessment phase you receive a written report with:

  * Findings and complexity rating
  * Recommended migration approach
  * Estimated effort and cost for full migration execution
  * Identified risks and mitigation recommendations



We review the report with you in detail. You leave with everything you need to make a go/no-go decision and plan your migration process.
