1.5. Upgrading JBoss Web Server
Upgrading JBoss Web Server is not supported. To upgrade to JBoss Web Server 3 from an older version, a fresh installation is recommended.
Important
If the RPM method was used to install JBoss Web Server 1.x or 2.x, it is not possible to remove JBoss Web Server 1.x or 2.x and install JBoss Web Server 3 on the same machine. Many configuration files from the old packages will be left on the system, and will create compatibility issues with the newer RPM packages. For the same reason, manually removing the old RPMs and installing the new ones is also not supported.
On a system where JBoss Web Server 1.x or 2.x was installed using the ZIP method, it is possible to remove the old version and install version JBoss Web Server 3 on the same system.
