Oracle E-Business Suite: Upgrades, Customizations and Migration
Oracle EBS is not on a deadline — Premier Support for 12.2 runs to at least 2037. That turns the question from "how fast do we escape?" into "upgrade and optimise, or migrate, and on what terms?" This is that decision, from the delivery side.
Overview
The most important fact about Oracle E-Business Suite in 2026 is that it is not going away. Oracle has committed Premier Support for EBS 12.2 through at least 2037, so the panic-driven "get off EBS now" narrative simply does not hold. The real work is deciding, deliberately, whether to keep upgrading and optimising your EBS estate or to migrate to Oracle Fusion Cloud or OCI — and when.
Either path runs through the same two things: your customizations and your integrations. A heavily modified estate with fragile, in-place customizations and file-based integrations is expensive to upgrade and risky to migrate. The same estate, with upgrade-safe personalizations and governed services, is straightforward to do either. That is why a CEMLI inventory and an integration review come before any roadmap decision.
The articles below cover the whole EBS lifecycle: how long 12.2 is really supported, the 12.1-to-12.2 upgrade, online patching with ADOP, managing customizations, integrating EBS properly, natural-language query on EBS, and the migration paths to Fusion Cloud.
