Migrate from Amazon RDS for Oracle to Aurora PostgreSQL or Amazon RDS for PostgreSQL using this self-service guide
Today, we’re introducing the Amazon Database Migration Accelerator (DMA) Connect program which is designed to help you migrate from Amazon Relational Database Service (Amazon RDS) for Oracle to Amazon Aurora PostgreSQL-Compatible Edition or Amazon RDS for PostgreSQL.
Migration to Amazon RDS for Oracle is a common first step for many customers making their foray into Amazon Web Services (AWS) managed databases. To get further benefits of AWS, you may want to consider moving to fully-managed Amazon RDS database services like Amazon RDS for PostgreSQL and Aurora PostgreSQL which help merge the flexibility and low cost of open source databases with the robust, enterprise feature sets of commercial databases.
To help you, the Amazon DMA Connect team has created a self-service offering to help you through your migration journey. We have created a guided path that starts with helping you self-assess the complexity of migrating your workload. We offer a migration guide that helps build a migration plan, webinars tailored for specific workloads, AWS-hosted weekly office hours to answer your specific questions, and community forum tracked by migration experts to help answer your migration-related queries.
Why Amazon DMA Connect?
The Amazon DMA Connect program features a vibrant worldwide community of migration experts who facilitate peer-to-peer learning by authoring blogs and e-books, leading office hours, hosting webinars, and supporting user forums. They are passionate about sharing their AWS technical expertise and helping you in your migration journey to AWS database services. The program can help you gain advanced knowledge and sharpen your technical delivery best practices.
As we continue to expand the scope of our database migration accelerator programs, we’re pleased to announce that this new program adds five new ways for you to engage with AWS migration experts. These offerings help you receive support for assessing workload complexity, planning for your migration, and performing the migration steps.
- Questionnaire – It all begins with an initial questionnaire to self-assess your workload. The questionnaire prompts you to think about not just the architecture, application, database, testing, deployment and operations, but also about your project and team setup.
- Guide – The guide provides step-by-step guidance to migrate your database and refactor your applications. It’s designed to help you use tools such as the AWS Schema Conversion Tool (AWS SCT), and AWS Database Migration Service (AWS DMS). It provides a 12-step process and, a migration plan, and covers topics such as reports, ETL, testing, DevOps and cutover.
- Webinar – Every week, a new webinar is posted to train on topics ranging from evaluating the right migration path for the application, to following a proven and repeatable database migration process, to architecture design and security. These pre-recorded sessions of 20-45-minute-length guide you with specific nuances for different use cases. You also have on-demand access to previously recorded webinars and can see the schedule of upcoming Webinar topics in the next section.
- Virtual office hours – Migration experts lead weekly, virtual office hours that are designed to answer questions from the community, in a video conference format. From technical advice to just getting started, this live, hour-long Q&A session with AWS migration experts is intended to support you and help answer questions as you start on your migration journey. These Office hours are held every Tuesday from 11:00 AM to 12:00 PM PST. You can join the Amazon Chime meeting here at the scheduled time. Meeting ID: 7451 21 9569
- Community Forums – Migration experts use a new, community-driven, question-and-answer service to help you remove technical roadblocks, accelerate innovation, and enhance operation. AWS re:Post enables you to ask questions about anything related to designing, building, deploying, and operating workloads on AWS, and get answers from community experts, including AWS customers, partners, and employees. re:Post automatically connects your question with migration experts, and is also integrated with AWS Support. It’s part of the AWS Free Tier and is available to anyone with an AWS account. Our experts moderate, create tags for relevant questions, answer questions, and/or provide additional resources on a regular basis. Choose one (or more) of the following tags when posting your question:
- DMA Connect
- Oracle to MySQL
- Oracle to Aurora
- Oracle to PostgreSQL
The questions posted with these tags also appear under the topics, “DMA Connect”, “Migration and Transfer” and “Database”.
