Oracle Migration Resources

From Monolith Platform to Modern Commerce


An Old Model in a New World Why Migrate? Why Now?

Recognized as a Leader by analysts Gartner and Forrester in the digital commerce space over a decade ago, Oracle has struggled to keep up with rapidly advancing technology. Their ATG platform was best-in-class for years, however the company retired it years ago, introducing Oracle Commerce Cloud (OCC) as their new, improved alternative.

Most ATG customers were unwilling to migrate to OCC for a variety of reasons. The consensus was that the new offering was a fundamental change from a platform they understood and trusted. It also didn’t have the same focus on the enterprise market or leverage the significant investments of the customers’  existing ATG platform.

As a result, Oracle was forced to continue supporting ATG. However, that support ended in May 2022. While there are third-party support vendors customers can use — the reality is ATG’s end of life makes it clear now that this is the right time for brands to move from this antiquated platform to a modern composable commerce solution.
