Migrate Oracle to Amazon Aurora PostgreSQL

Looking for a reliable partner to migrate Oracle to Amazon Aurora PostgreSQL or RDS PostgreSQL? We know how to migrate your Oracle database to AWS in a short period of time.

Why migrate Oracle to Amazon Aurora PostgreSQL?

Running Oracle databases in an on-premises environment presents customers with many challenges, such as increasing license and maintenance fees, and the need to upgrade from older versions to avoid compliance problems. Growing companies require cost-effective databases that are fast enough to keep pace with their expanding business, and enable automated processes to replace time-consuming administrative tasks.

Modernized cloud database solutions can help address these issues. We are a leader in database cloud migration, data services management, application modernization, and delivery of solutions for new services such as analytics and the Internet of Things (IoT). We have the expertise to help customers of all sizes successfully migrate Oracle to Amazon Aurora PostgreSQL, and the know-how to optimize performance following cloud adoption.

We are ready to guide you through the entire migration process and help optimize your Amazon Aurora environment after cloud adoption. Together we will establish a solid database foundation on Amazon Web Services (AWS), and leverage our unique expertise to help you integrate a wide range of AWS services and increase business flexibility.

Determining which Database and infrastructure technology is a best fit in AWS

There are many approaches to database technology in AWS from infrastructure EC2 to managed Aurora/RDS and the many flavors of database server that can be supported here.

Key here is understanding these points:

  • What is your current database and infrastructure technology and what is the appropriate match in AWS?
  • What resources do you have to support your database technology in AWS? Is Aurora, RDS, or EC2 the correct approach?
  • What is your HA/DR approach and can it be mapped to AWS
  • What is your data Egress and Ingress and how will that affect your charges

DB Best can help you evaluate your current workload and direct you to the best technology in the AWS.

Choosing which workloads to move to the cloud

We take a data-centric approach to determine which workloads are most appropriate for the cloud.  We start with data collection that gives us a profile of each workload environment such as CPU, RAM, etc.  We also gather performance metrics over a period of time using our agentless DBMSys software.  We also work with our customers to understand the business needs / restrictions of each workload to determine a list of potential candidates that can be moved to the cloud.

Migrating away from your current data solution

Traditionally, this means that a switch from one data platform to another. However, just switching the nameplate on the back-end DB server may not be the best solution. Some data patterns and use cases may have a better fit for a NoSQL or Data Lake solution.

DB Best Architects are trained to spot these patterns and discuss with the customer another approach that may be a better fit or be able to leverage new technology such as IoT devices.

How can I migrate terabytes of data to the Amazon cloud?

Imagine you have a 80 TB database that needs to be extracted and imported into AWS Redshift or Aurora database. Normally, it would take up to several weeks for extracting and migrating such databases over internet. DB Best has worked with Amazon in exposing a Snowball Edge configuration option in the Schema Conversion Tool. With this feature, you can hookup a Snowball Edge device to your on-premises database, extract data and upload data to the Snowball Edge and send it back to Amazon for completing the data import process during your data warehouse migration to AWS.

DB Best Architects are trained to help you in configuring the Snowball Edge, in extracting and help you in completing the data transfer much faster.

Building an AWS stack with multiple layers can be time-consuming and error prone

DB Best’s architects can help you in automating the entire stack creation process leveraging AWS’s CloudFormation templates using command line scripts. These scripts take few command line parameters and setup your VPC, subnets, ELB, Aurora clusters, RDS & EC2 instances, databases, Auto-scaling groups, creating S3 buckets and uploading data, database restores and health checks.

A leading education SAAS provider improved performance and reduces costs with Aurora PostgreSQL

Increase in license fees leads to cloud adoption

One example of a DB Best success story can be found in a customer that works with higher education institutions to deliver student success in 40 countries around the world. This customer was facing an increase in licensing fees and limited scalability options in their current IaaS environment. Moving to a PaaS offering would address these challenges.

The customer’s legacy architecture included separate applications, all being run on-premises, with an Oracle database back-end, but they did not want to expand their Oracle licensing obligations and incur additional costs. They were also seeking increased flexibility and wanted to develop data warehousing and big data analytics. They decided to work with DB Best to help them achieve these goals.

DB Best analyzed the customer’s existing architecture and created a proposal to migrate and merge these applications on AWS, replacing Oracle. Using the AWS SCT, DB Best migrated nearly
20,000 stored procedures, more than 15,000 functions, 1,500 views, and 2,200 datatypes from Oracle to AWS.

Improved query time by nearly 400x

DB Best developed a PaaS-based solution on AWS that enabled the customer to extend the functionality of their applications without having to manage the infrastructure. This allowed the customer to continue to innovate and increased their responsiveness to the needs of the institutions they serve. It also fostered an environment of rapid application development and scalability.

As a result, all of the customer’s data now resides on AWS, in a more flexible environment with greater capacity for future analytics workloads. The AWS-based architecture that DB Best helped this customer migrate to has helped them reduce query execution times by nearly 400x (from 33 minutes to under five seconds), and enabled them to greatly cut the amount of time spent on
application development cycles.

DB Best leveraged the AWS platform for this customer to meet requirements such as automatic scaling, performance, and storage.

Automated tools accelerate cloud adoption

To help our customers migrate from Oracle to Amazon Aurora, DB Best uses the automated tools they have developed to help accelerate cloud adoption. One of the featured tools we often employ is the AWS Schema Conversion Tool (SCT), which is used to compile statistics from the source database, make recommendations on finetuning, and perform analysis to forecast how Amazon Aurora can be optimized for a customer. The AWS SCT identifies potential problem areas during migration planning, determines the possible effects on the schema conversion process, and creates a strategy to validate the data.


DB Best also has expertise using the AWS Database Migration Service (DMS) to help customers move their databases to the cloud quickly and securely. The AWS DMS supports migrations between different database platforms, such as moving from Oracle to Amazon Aurora, and helps to minimize downtime during the migration process. DB Best works with the customer DBAs to strategically plan the migration and optimize capabilities on AWS.

These are the tools that we helped Amazon build or built ourselves to help automate migration from Oracle to Amazon Aurora by analyzing all of the applications that interface with the Oracle database to confirm data conversion.

DB Best’s unique approach and methodology include performance testing and benchmark metrics they have developed to deliver project success.

We are the only AWS partner who can say we've migrated more databases to AWS RDS, Amazon Aurora, and Amazon Redshift than any other partner in the world using AWS Database Migration Service (DMS) and Schema Conversion Tool (SCT).
