One of the benefits of using SAP BTP ABAP Environment is that updates and upgrades are applied by SAP to the systems in quite a high frequency and close to the corresponding release time.
Find the latest known schedule of Major Upgrade Windows and Weekly Maintenance Windows for 2025 in this blog post.
Major Upgrade Windows
As in 2024, the SAP BTP ABAP Environment will have 4 Major Upgrade Windows in 2025. These 24 hours of potential system unavailability are used to upgrade the systems to the next major version.
