Analyzing Migration Project Efforts and Crafting the Project Plan — Part 3
Welcome to the third blog post in the overview series dedicated to our 12-step Migration and Modernization Methodology that was adopted by AWS. In our first and second blog posts, we explored the critical role of defining workloads in migration projects and laid out the process of capturing the current architecture and designing the future […]
Workload Definition Shapes the Migration & Modernization Roadmap — Part 1
Welcome to the first blog post in the overview series dedicated to our 12-step Migration and Modernization Methodology that was adopted by AWS. In any migration or modernization project, it’s crucial to start with a clear understanding of the system’s components and their relationships. This is where workload definition comes into play. Defining workloads correctly […]
Migrating from Oracle to SQL Server for a food manufacturing company
ABCloudz recently helped The Morning Star Company, one of the world’s largest producers of tomato products, migrate their Oracle database to SQL Server. The Morning Star Company operates three processing facilities in California, handling nearly 10% of the global tomato production. Their IT infrastructure included both Oracle and SQL Server databases, but due to the […]

Database migration with AWS SCT: Solutions for typical conversion issues
Migrating Oracle databases to PostgreSQL or MySQL with AWS Schema Conversion Tool (AWS SCT) can present a range of challenges, from unsupported data types to limitations in automated code conversion and potential performance issues. AWS SCT offers powerful capabilities to automate these migrations, but it may not always deliver optimal results or handle complex Oracle […]
Database migration with SSMA: Handling typical conversion issues
Migrating databases from Oracle to Microsoft SQL Server can be a complex endeavor, especially when it comes to dealing with differences in schema structures, data types, and specific SQL clauses. The SQL Server Migration Assistant (SSMA) is a robust tool designed to automate these migrations and minimize manual effort. However, SSMA might not always produce […]
Handling null and empty string differences in Oracle and PostgreSQL
When migrating from Oracle to PostgreSQL, one of the most important differences to consider is the treatment of null and empty string values. In Oracle, null and empty string are treated as the same entity, but in PostgreSQL, they are distinct. Failing to account for this distinction during migration can lead to logical errors and […]
Handling PostgreSQL Routines with More Than 100 Arguments
When working with PostgreSQL, database developers may encounter a limitation when attempting to create routines with more than 100 arguments. PostgreSQL enforces this restriction by setting FUNC_MAX_ARGS to 100 during the server build. Although this limitation is rarely an issue, complex procedures, particularly those migrated from Oracle, may have a significantly higher number of arguments. […]
Optimizing Date and Time Conversion in Oracle to SQL Server Migration
Migrating databases from Oracle to SQL Server can be a daunting task, especially when dealing with date and time data. While tools like the SQL Server Migration Assistant (SSMA) offer automated solutions, relying solely on these tools might not always yield the best performance. In this blog, we share examples of how to optimize conversion […]
How to Optimize Oracle-to-PostgreSQL Migrations Using AWS SCT Extension Pack
The AWS SCT Extension Pack is designed to emulate Oracle’s system functions, procedures, and other database objects within PostgreSQL. This emulation is achieved by creating a special schema in PostgreSQL, named aws_oracle_ext, where these functions and objects are stored. This pack simplifies migration by replacing Oracle-specific calls with their PostgreSQL equivalents, ensuring that the code […]

EDW to Azure Databricks Migration
ABCloudz recently completed a significant project migrating an Enterprise Data Warehouse (EDW) from an on-premises SQL Server 2014 to Azure Databricks for a leading global retailer operating 3,000 offline stores across 40 countries. This migration was essential for addressing physical server limitations and outdated technology that hindered data processing and storage capabilities. Embracing Big Data […]
