Update a Wildfly / JBoss EAP 7 Installation from 7.17 to 7.18

The following steps describe how to update the Camunda artifacts on a Wildfly/JBoss EAP 7 in a shared process engine scenario. Throughout the procedure, refer to the update guide.

If not already done, download the Camunda Platform 7.18 Wildfly distribution.

The update procedure takes the following steps:

  1. Update the Camunda Platform modules.
  2. Update optional Camunda Platform modules.
  3. Update Camunda web applications.

Whenever the instructions are to replace a module, delete the previous version of the module first to avoid orphan jars.
