Overview

Incompatible subsystems, such as messaging or web can be migrate to their counterparts messaging-activemq or undertow on a subsystem per subsystem basis, as described below.

Procedure

Get a copy of the EAP 6 configuration file in the same "configuration" directory its EAP 7 counterpart exists. The migration procedure works for both standalone-*.xml or domain.xml. In case of domain mode, we will need to navigate in CLI to the required profile, as shown below.

Name the configuration file suggestively, something like "domain-eap6-to-migrate.xml".

Start the EAP 7 instance in admin mode, in top of the file to be migrated.

cd $JBOSS_HOME/bin
./domain.sh --admin-only --domain-config=domain-eap6-to-migrate.xml

Connect with CLI:

cd $JBOSS_HOME/bin
./jboss-cli.sh -c

Navigate to the subsystem in question. This is done differently in standalone and domain mode.

/profile=full-ha
./subsystem=messaging:describe-migration

Perform the migration:

./subsystem=messaging:migrate

The result should be similar to:

{
    "outcome" => "success",
    "result" => {"migration-warnings" => []},
    "server-groups" => undefined
}

Shut down the server.

The domain-eap6-to-migrate.xml will contain the migrated configuration.
