2 Weeks Assessment: Migrating Oracle to Azure Database for PostgreSQL

Database migration can be a complex and time-consuming process for any IT team exploring to do it by themselves, and without proper Assessment and migration plan the decision making gets even harder, this is where Quadrant adds the value by bringing a team of experts and established processes and automation tools like QMigrator to speed up the Assessment and provide accurate migration plan by analyzing and evaluating the Applications and Databases that needs to be migrated from on-Premise to the cloud.

More and More organizations are shifting to open-source databases like PostgreSQL in the cloud to benefit from.

• Improved manageability.
• High Scalability.
• High availability and business continuity.

Architecture Evaluation

We evaluate architecture of your Applications, Interfaces and Workloads in relation to Databases in scope and propose future Application architecture solutions on Cloud.

Assessment of your Oracle Databases

The first step is to assess the size and complexity of the Oracle database. QMigrator scans the Oracle source database and workloads and helps us to provide precise estimation of the migration effort. This assessment will help to determine the potential challenges migrating to PostgreSQL and formulate migration strategy.

Application Assessment

Application assessment is to determine if any changes are required due to change of database. This may include updating configuration settings, modifying the application code, Data Accees Layer changes or updating embedded SQL.

After the Above Steps are complete, we will create a detailed Assessment Executive Summary report based on the QMigrator automated outputs and assessment team observations, which includes timelines, resources, contingency measures, and financials including infrastructure cost based on the on-prem capacity utilization. Our Assessment report also includes alternate migration methods, testing and validation procedures, and post-migration support, enabling you to take appropriate decisions on the following aspects as well.

Database Migration and Integration

Rehosting : Whether a Lift and Shift be the right approach for the database migration with minimal or no code changes

Re-Platforming : Whether moving from Licensed Databases to Open-Source Database like Azure PostgreSQL benefits your organization.

Rearchitecting : Whether Database architecture changes like partitioning, Hyperscale, NoSQL, Microservice or ADL is the way forward.

Our Executive Assessment Summary also represents the comparison of current architecture of your Applications, Interfaces and Workload impacts to future Application architecture on Cloud.

Benefits of an Assessment

• Identification of risks and challenges : Assessment helps to identify potential risks and challenges associated with the migration, such as data loss, downtime, compatibility issues, or performance problems.
• Evaluation of the migration method : The assessment evaluates the suitability of the migration method and tools for the specific migration scenario. It helps to select the optimal migration strategy based on the size, and complexity.
• Cost estimation : The assessment provides an estimate of the costs associated with the migration, including licensing, hardware, software, and labor costs.
• Data mapping and schema conversion : The assessment identifies the differences between the source and target database platforms and maps the data types in the source database to their equivalent data types in the target database. It also identifies schema differences and determines the best approach to convert the schema from the source to the target database.
• Application assessment : The assessment evaluates the application that uses the database to determine if any changes are required to support the migration. which includes modifying the application code, or updating scripts.
• Testing and validation : Outlines the testing and validation plan to ensure that the migrated data is accurate and consistent with the source database. This may include functional and performance testing, as well as user acceptance testing.
• Migration plan development : Based on the assessment findings, a detailed migration plan is developed that includes timelines, resources, and contingency measures.

Overall, a database migration assessment provides valuable insights into the migration process, identifies potential risks, and challenges, and helps to develop a detailed migration plan. It ensures that the migration is cost-effective, minimizes downtime, and maintains data integrity.

The Timeline mentioned in this offering may vary depending on several factors one of the prime factors is the database size and associated code objects, however an initial assessment will give the near accurate timeline.
