New Approaches to Migrating From Oracle to Postgres in the Cloud

February 20, 2019

Organizations choose to adopt cloud-based technology services due to their accessibility, reliability and ease of use. Database technology is no exception, with many organizations adopting Postgres in the Cloud for greater control over their cloud environments and databases.

For Oracle® users, migrating from Oracle to a cloud-based Postgres solution can seem like a difficult undertaking. Whether it’s due to the sheer number of databases or the terabytes of information associated with them, the idea of moving from a tried-and-true service to a new cloud-based solution can seem like a risky challenge.

These reservations are misguided. The efficiency, comparability and cost savings offered through Postgres in the Cloud can greatly enhance the database operations of any organization. By taking a fresh look at the Oracle migration process, organizations can see just how easy it is for Oracle databases to move to a cloud-based Postgres solution with layers of full compatibility.

If you’re looking to migrate your Oracle database operations into Postgres in the Cloud, consider these new approaches for a streamlined, efficient experience:


Begin Migrations With Easy Databases

Migrating from Oracle to Postgres in the Cloud may seem daunting, especially when an organization is dealing with hundreds or thousands of different databases. But the migration process isn’t a single task that’s waiting to be tackled — instead, it’s better to spread the project out over a set period to tackle the migration one step at a time.

The migration process should begin by identifying a small portion of databases that aren’t linked to mission-critical tasks and can be easily moved to Postgres. Ideally, this should account for around 10 percent of your databases in use. Starting with easy databases gives your team hands-on experience learning the Postgres platform with real-world data. During this step of the migration process, users will familiarize themselves with how Postgres works without interfering with any data sets that power an organization’s most important applications.

With the EDB Postgres Migration Portal, built-in Oracle compatibility features make it easy to identify Oracle databases that will transfer with ease. Through a user-friendly color-coded interface, users can upload schemas to determine which databases can migrate with little or no effort (green), which ones require a certain amount of tweaking (yellow) and which ones require more advanced efforts for full compatibility (red).


Choose an Oracle-Compatible Version of Postgres

Organizations that continue to rely on Oracle databases often require enterprise-specific functionality. While the open source Postgres platform is flexible and expansive, many enterprise-level database features such as high availability are not built directly into the platform itself. This is a feature, not a bug: The Postgres community is committed to developing and refining the Postgres platform itself, making the core software adaptable enough to be useful in any situation.

EDB Postgres enhances the open source Postgres platform by offering a full suite of enterprise-ready tools that are compatible with Oracle databases. The EDB Postgres Advanced Server offers a full layer of Oracle compatibility that replicates common Oracle functionalities. This eliminates the need for major manual code rewrites that can often lead to crippled functionality or a drawn-out manual updating process.


Get Practice

One of the best ways to understand how to move an Oracle database into Postgres in the Cloud is through hands-on experience. Whether you’re already well-versed in Oracle or you’re a DBA looking to try a new cloud-based solution, being able to experience Postgres and handle an Oracle database can help ensure a future database migration goes smoothly.

EDB proudly offers a full series of online training courses to help users learn the fundamentals of Postgres, practical skills for real-world scenarios and Oracle compatibility and migration functionalities. Spread out over several modules with dozens of different real-world demos and exercises, EDB’s self-guided training can help any DBA fully understand the ins and outs of Postgres before tackling an actual Oracle migration. The training culminates in the EDB Postgres Advanced Server 9.6 Associate Certification, which enables DBAs to earn the EDB Certified Associate designation that certifies a user’s expertise in maintaining and managing the EDB Postgres Advanced Server.
