What is a Migration Assessment?
A pre-migration database audit is the first and most critical stage of any cross-DBMS migration — a move to a different database engine, such as Oracle to PostgreSQL. Without it, you are moving blindly: it is impossible to accurately predict scope, complexity, or risk.
A database audit answers key business questions:
Scope
How many objects, lines of code, and data need to be migrated — and what the overall migration scope looks like.
Compatibility
What can be migrated seamlessly, and what lacks a direct equivalent in the target database and will require manual refactoring.
Integrations
Which applications, ETL flows, reports, and scheduled jobs depend on the database, and what each will require.
Risks
Bottlenecks, unsupported constructs, and complex integrations that would otherwise only surface during the project.
Approach
The level of automation possible, the expertise required, and the best approach for handling complex migration scenarios.
Architecture
Recommendations for the target database and infrastructure, including key architectural changes needed for a successful migration.
The more accurate the database migration analysis is at the start, the fewer surprises you face in the middle. We don't guess the numbers — we measure them.
What you get
We turn database migration analysis into actionable numbers.
Key findings
Even before the project starts, you understand the complexity, volumes, and all the nuances of your migration — allowing you to make decisions based on facts.

What is a pre-migration audit and database migration assessment?
It is the analysis of the source database before migration begins. It evaluates data and SQL code volume, complexity, integrations with other systems, and migration risks. The result is a clear understanding of the project's timeline and required effort before it starts.
How much does a database migration assessment cost?
The cost of the detailed assessment depends on the size and complexity of your database infrastructure. Contact us, and we will provide a quote based on your specific requirements.
Which databases do you assess for migration?
Oracle, MS SQL Server, PostgreSQL, MySQL, IBM Db2, Sybase ASE, Informix, and others.
How long does a database migration assessment take?
A detailed assessment and planning phase typically takes 2–4 weeks, depending on the complexity of your system.
How do you estimate the complexity of migrating Oracle to PostgreSQL?
Our experts analyze your Oracle database metadata, code, and integration points to gather vital statistics. Based on this audit, we evaluate what can be transitioned smoothly and where manual architectural adjustments are required.
What happens after the database audit is completed?
We agree on the plan, timelines, and costs. Once approved, we move on to the actual migration phase: transferring the schema, business logic/code, and data.
How do I start the database migration assessment process?
Leave a request on our website. Our team will schedule a call to understand your system, evaluate the initial scope, and propose a plan for the detailed audit.
