Overview - WildFly 10

This Release Note covers all point releases for WildFly 10 that are offered by eApps. Upgrade instructions are included.

WildFly is the continuation of the JBoss Application Server (JBoss AS) project. It is essentially JBoss AS 8, but the project was renamed by Red Hat in order to differentiate the open source JBoss AS project from the commercial Red Hat JBoss Middleware project.

WildFly 10 and above is only available for Virtual Servers running CentOS 6 or CentOS 7. If you are on a CentOS 5 (Webmin) or CentOS 4 (VPS) plan and need WildFly, you will need to migrate to a CentOS 6 or CentOS 7 plan. Contact eApps Sales for more information.

WildFly 10 and above requires Java SE 8. It will not run with Java SE 6 or Java SE 7.

Warning Along with the name change, WildFly is a major update to the existing JBoss AS 7. This release has introduced new functionality and significant changes to the existing Application Server. If you are upgrading from any prior version of JBoss to WildFly, there is a HIGH RISK of data loss and downtime if you do not carefully test your existing application with this new version.

eApps recommends, as a best practice, to maintain a staging server where you can test software upgrades before moving them into production. This approach will allow you to minimize the risk of data loss and downtime of your production service when performing software upgrades. If necessary, you can rebuild your staging Virtual Server on demand so that you have a fresh installation to test on. If you need more information about setting up a Virtual Server for staging or testing, please contact eApps Sales.

IMPORTANT: WildFly 10 has an extensive list of new features and changes. See the Official WildFly 10 Release Notes for a list of changes that may cause issues when upgrading: WildFly 10 Release Notes. Please read this document carefully to understand all the changes in WildFly 10. Upgrading to this version may significantly impact the operation of your database and applications.

How to Upgrade

It is your responsibility to ensure that your application will work on the newer version of WildFly. There may be incompatibilities that will affect how your application works. Please make sure that you have read the official Release Notes and Changelog, and have done any necessary testing before upgrading a production application.

Before upgrading WildFly make a backup of your database. Follow the instructions for your database: MySQL, MariaDB, or PostgreSQL.

You should also make a backup of your application, your configuration, and any tunings or changes you have made. If you do not have current backups and something goes wrong during the upgrade process, you could have data loss.

Warning The upgrade from JBoss (any version) or any previous version of WildFly to WildFly 10 has to be done manually, there is no way to automate the process. Please read the upgrade instructions for your scenario and proceed accordingly. Failure to follow the correct upgrade instructions can result in data loss and extended downtime for your applications and users.

JBoss 6 or JBoss 7 to WildFly 10

There is no direct upgrade path from JBoss (any version) to WildFly (any version). To upgrade from any version of JBoss to WildFly 10 you will need to make a backup of your existing application, database, configuration, and any customizations and tunings, and then uninstall JBoss and install WildFly 10. Once WildFly 10 is installed, you will need to redeploy your application and all configurations and databases.

It is highly recommended that you provision a test Virtual Server, install WildFly 10 and your database server, and then copy your existing application, configurations, and database to the test VS. This will allow you to fully test that your existing application will work with WildFly 10 before moving it into production. Once you have completed your testing you can then upgrade your production Virtual Server, and then cancel the test VS.
