The Oracle Solaris blog has many examples of the modern technology that make Oracle Solaris 11.4 the trusted OS for mission-critical enterprise workloads. However, if you still have workloads running on older releases of the Oracle Solaris operating system, this article is for you.
In order to give you additional time to plan and move your workloads to the latest release of Oracle Solaris, Oracle has postponed the end date of Extended Support for Oracle Solaris 10 and 11.3 to January 2027. In addition, the end date of Extended Support for Oracle Solaris Cluster 3.3.x software and Premier Support for Oracle Solaris 10 Containers software have also been postponed to January 2027. These actions are in line with Oracle’s ongoing commitment to our customers and their investment in Oracle Solaris technology for enterprise deployments.
When planning your move to the Oracle Solaris 11.4 operating system, note that not only it offers the latest innovations, security, and best performance, but also our Binary Compatibility Guarantee to run older workloads. In fact, if an older application uses the well-defined Oracle Solaris interfaces (Footnote1) we guarantee that you can run it on new SPARC servers. For example, you can take an application that originally ran on Oracle Solaris 8 on a legacy SPARC server and run it on Oracle Solaris 11.4 on our newest SPARC T8 servers.
After the end of Extended Support in January 2027, Oracle may offer Market Driven Support (MDS) for these software products. Of course, you can still run them under Sustaining Support for a long period of time. For more details on the dates for the Oracle Solaris support please refer to the Oracle and Sun System Software and Operating Systems Oracle Lifetime Support Policy (page 23 for Oracle Solaris Cluster, and page 40 for Oracle Solaris).
