Backward compatibility

OpenCms 11.0 is backward compatible with all 10.5, 10.0, and 9.5 versions. Templates and other OpenCms developed code from these versions should work mostly "out of the box" with version 11.0.

Notice for users of Alkacon OCEE: Current release versions of Alkacon OCEE are not compatible with OpenCms 11.0. Further information about the future of OCEE will be available soon on the Alkacon website.

Compatibility with Java versions, servlet containers and databases

OpenCms 11.0 has been written and tested for Java 11 and Java 8. We have tested with ORACLEs JDK as well as OpenJDK. OpenCms should run with all compliant JVMs.

We have tested this release on the Tomcat servlet engine, which we recommend. OpenCms works "out of the box" with Tomcat 9, 8.5 or 8. Others have reported deploying OpenCms successfully on other servlet containers like JBoss, WildFly, WebLogic, WebSphere, GlassFish and Resin.

On the database side, we provide support for MySQL, MariaDB, Oracle, PostgreSQL, MS SQL Server, DB2 and HSQLDB.
