The domain migration consists in migrating the source server's domain content and domain/host configuration files, to the target server. This migration task is optional, and in case the tool is running in interactive mode a prompt will first ask to confirm its execution:
In case the domain migration proceeds, the tool will start by migrating the source server's domain content, a cyphered repository used to store data such as deployments and deployment overlays, referenced by domain/host configurations. Both servers use a similar content repository, thus the migration of such data merely consists of finding, and copying such content among servers.
If you are running in non-interactive mode, the JBoss Server Migration tool will migrate all listed domain configuration files.
If you are running in non-interactive mode, the JBoss Server Migration tool will migrate all listed host configuration files.
The domain migration may be customized, by configuring the migration environment:
Domain Configuration File Migration
The migration of a domain configuration file consists of copying the source configuration file to the target server, and then apply the relevant changes for such configuration to work correctly in the target server, and also take advantage of the target’s server’s new functionality:

Remove Unsupported Subsystems
The following WildFly 8 subsystems are not supported by JBoss EAP 7:
-
batch (configuration namepace: urn:jboss:domain:batch:*, extension module: org.wildfly.extension.batch)
All unsupported subsystems configurations and extensions are removed from migrated server configurations.
The console indicates which unsupported subsystem configurations and extensions are removed from each server configuration:
19:01:26,806 INFO [org.jboss.migration.core.task.ServerMigrationTask#14] (main) Removed the following unsupported extensions: [org.wildfly.extension.batch]19:01:26,806 INFO [org.jboss.migration.core.task.ServerMigrationTask#14] (main) Removed the following unsupported subsystems: [urn:jboss:domain:batch:1.0]
Migrate Referenced Modules
A migrated domain configuration may reference, i.e. depend on, modules which are not installed in the target server, and in such case(s) the tool automatically migrates the referenced module(s), from the source server. Beyond that, any module that a referenced module depends on, directly or not, and is not installed in the target server, is automatically migrated too.
A module will be migrated when referenced by:
-
a Datasource subsystem configuration, as datasource driver(s) module
-
an EE subsystem configuration, as a global module
-
a Naming subsystem configuration, as Object Factory module
-
a Messaging subsystem configuration, as JMS Bridge module
(Video) Jboss (or) Wildfly Application Server Migration
Whenever a module is migrated, a message indicating the module's id should be printed in the migration console/log, as exampled below:
03:25:31,218 INFO [org.jboss.migration.core.task.ServerMigrationTask#19] (main) Module cmtool.datasources:main migrated.03:25:31,222 INFO [org.jboss.migration.core.task.ServerMigrationTask#20] (main) Module cmtool.ee1:main migrated.03:25:31,225 INFO [org.jboss.migration.core.task.ServerMigrationTask#21] (main) Module cmtool.ee2:main migrated.03:25:31,229 INFO [org.jboss.migration.core.task.ServerMigrationTask#22] (main) Module cmtool.naming:main migrated.
It's possible to exclude the migration of specific module(s), by specifying the id(s) in the environment property named modules.excludes.
Migrate jacorb Subsystem
The jacorb subsystem is deprecated on EAP 7, and the tool migrates its configurations to the EAP 7subsystem that replaces it, named iiop-openjdk.
The legacy subsystem migration is done without any interaction with the user, and any issue with the legacy subsystem configuration, e.g. missing functionality, results in a warning shown in the migration console and log(s). A successful migration of the legacy subsystem configurations is indicated by the following messages:
07:20:53,357 INFO [org.jboss.migration.core.ServerMigrationTask#331] (main) Migrating subsystem jacorb configurations...07:20:53,437 INFO [org.jboss.migration.core.ServerMigrationTask#332] (main) Subsystem config /profile=full-ha/subsystem=jacorb migrated.07:20:53,487 INFO [org.jboss.migration.core.ServerMigrationTask#335] (main) Subsystem config /profile=full/subsystem=jacorb migrated.07:20:53,534 INFO [org.jboss.migration.core.ServerMigrationTask#336] (main) Extension org.jboss.as.jacorb removed.07:20:53,534 INFO [org.jboss.migration.core.ServerMigrationTask#331] (main) Subsystem jacorb configurations migrated.
Please note that the Migration Environment may be configured to skip jacorb's subsystem migration, by setting environment property named subsystem.jacorb.migrate.skip as true.
Migrate messaging Subsystem
The messaging subsystem is deprecated on EAP 7, and the tool migrates its configurations to the EAP 7subsystem that replaces it, named messaging-activemq.
The legacy subsystem migration is done without any interaction with the user, and any issue with the legacy subsystem configuration, e.g. missing functionality, results in a warning shown in the migration console and log(s). A successful migration of the legacy subsystem configurations is indicated by the following messages:
07:20:53,796 INFO [org.jboss.migration.core.ServerMigrationTask#343] (main) Migrating subsystem messaging configurations...07:20:53,902 INFO [org.jboss.migration.core.ServerMigrationTask#344] (main) Subsystem config /profile=full-ha/subsystem=messaging migrated.07:20:53,983 INFO [org.jboss.migration.core.ServerMigrationTask#347] (main) Subsystem config /profile=full/subsystem=messaging migrated.07:20:54,009 INFO [org.jboss.migration.core.ServerMigrationTask#348] (main) Extension org.jboss.as.messaging removed.07:20:54,009 INFO [org.jboss.migration.core.ServerMigrationTask#343] (main) Subsystem messaging configurations migrated.
Please note that the Migration Environment may be configured to skip messaging's subsystem migration, by setting environment property named subsystem.messaging.migrate.skip as true.
Update infinispan Subsystem
The infinispan subsystem configurations are updated to better match the EAP 7 default configurations:
-
adds the server cache, present on EAP 7 default configs
-
fixes the module name in hibernate cache configuration
The changes on the subsystem configurations are fully automated, the tool console and log(s) will merely indicate these changes were done, e.g.:

Please note that the Migration Environment may be configured to customise the process of updating the subsystem configuration:
-
fully skip the subsystem config update, by setting environment property named subsystem.infinispan.update.skip as true
-
don't add the server cache, by setting environment property named subsystem.infinispan.update.add-infinispan-server-cache.skip as true
-
don't fix the module name of hibernate cache, by setting environment property named subsystem.infinispan.update.fix-hibernate-cache-module-name.skip as true

Update Unsecure Interface
The tool updates the unsecure interface configuration to match JBoss EAP 7 default configurations.
The configuration changes are fully automated, and the following messages, in the migration console and log(s), indicate that such changes were done as expected:
07:20:57,083 INFO [org.jboss.migration.core.ServerMigrationTask#432] (main) Interface unsecure inet address value set as ${jboss.bind.address.unsecure:127.0.0.1}. The Migration Environment may be configured to skip the Unsecure interface update, by setting environment property named interface.unsecure.update.skip as true.
Setup Private Interface
JBoss EAP 7 default configurations uses a new private interface on all jgroups socket bindings, and the tool automatically updates any migrated configuration with jgroups socket-bindings, to follow same setup.
The following messages in the console indicates this configuration update:
07:20:57,102 INFO [org.jboss.migration.core.ServerMigrationTask#434] (main) Interface private added.07:20:57,121 INFO [org.jboss.migration.core.ServerMigrationTask#436] (main) Socket binding /socket-binding-group=full-ha-sockets/socket-binding=jgroups-mping interface set to private07:20:57,140 INFO [org.jboss.migration.core.ServerMigrationTask#436] (main) Socket binding /socket-binding-group=full-ha-sockets/socket-binding=jgroups-tcp interface set to private07:20:57,159 INFO [org.jboss.migration.core.ServerMigrationTask#436] (main) Socket binding /socket-binding-group=full-ha-sockets/socket-binding=jgroups-tcp-fd interface set to private07:20:57,181 INFO [org.jboss.migration.core.ServerMigrationTask#436] (main) Socket binding /socket-binding-group=full-ha-sockets/socket-binding=jgroups-udp interface set to private07:20:57,202 INFO [org.jboss.migration.core.ServerMigrationTask#436] (main) Socket binding /socket-binding-group=full-ha-sockets/socket-binding=jgroups-udp-fd interface set to private07:20:57,223 INFO [org.jboss.migration.core.ServerMigrationTask#438] (main) Socket binding /socket-binding-group=ha-sockets/socket-binding=jgroups-mping interface set to private07:20:57,244 INFO [org.jboss.migration.core.ServerMigrationTask#438] (main) Socket binding /socket-binding-group=ha-sockets/socket-binding=jgroups-tcp interface set to private07:20:57,262 INFO [org.jboss.migration.core.ServerMigrationTask#438] (main) Socket binding /socket-binding-group=ha-sockets/socket-binding=jgroups-tcp-fd interface set to private07:20:57,281 INFO [org.jboss.migration.core.ServerMigrationTask#438] (main) Socket binding /socket-binding-group=ha-sockets/socket-binding=jgroups-udp interface set to private07:20:57,300 INFO [org.jboss.migration.core.ServerMigrationTask#438] (main) Socket binding /socket-binding-group=ha-sockets/socket-binding=jgroups-udp-fd interface set to private
The Migration Environment may be configured to skip adding the private, by setting environment property named interface.private.setup.skip as true.
Remove Permgen Attributes From JVMs
The usage of Permgen attributes in JVM configurations is deprecated, and the tool removes these from all JVM configurations, for all server groups.
07:20:57,629 INFO [org.jboss.migration.core.ServerMigrationTask#453] (main) Removal of permgen attributes from JVM configs starting...07:20:57,695 INFO [org.jboss.migration.core.ServerMigrationTask#454] (main) Permgen removed from JVM /server-group=main-server-group/jvm=default07:20:57,731 INFO [org.jboss.migration.core.ServerMigrationTask#455] (main) Permgen removed from JVM /server-group=other-server-group/jvm=default07:20:57,731 INFO [org.jboss.migration.core.ServerMigrationTask#453] (main) Removal of permgen attributes from JVM configs done.
The Migration Environment may be configured to skip adding this configuration update, by setting environment property named jvms.remove-permgen-attributes.skip as true.
Migrate Deployments
With respect to domain configuration's deployments, the migration tool is capable of migrating the persistent deployments it references, and related deployment overlays as well.
Please be warned that the migration of a deployment, or deployment overlay, merely consists in installing related file resources in the target server, and possibly update the migrated configuration. The tool will not assert if such resources are compatible with the target server, which means these may not deploy/work as expected, or not deploy/work at all! To analyse a deployment, with respect to compatibility among different JBoss servers, it is strongly recommended usage of JBoss Windup.
Migrate Persistent Deployments
When migrating a domain configuration, the migration tool will search for any persistent deployments it refers, and print the results in the migration console/log:
03:19:08,997 INFO [org.jboss.migration.core.task.Task#74] (main) Persistent deployments found: [cmtool-helloworld3.war, cmtool-helloworld4.war, cmtool-helloworld2.war, cmtool-helloworld1.war]
And in interactive mode you will then see the following prompt:
Migrate all persistent deployments found?yes/no? y
-
If you say yes, or y, all found deployments are migrated.
-
If you say no, or n, you receive a prompt asking to confirm the migration, for each listed deployment:
Migrate persistent deployment 'cmtool-helloworld3.war'?yes/no?
-
If you say yes, or y, the deployment is migrated.
-
If you say no, or n, all references to the deployment are removed.
04:31:43,562 INFO [org.jboss.migration.core.task.ServerMigrationTask#555] (main) Removed persistent deployment from server group /deployment=cmtool-helloworld4.war04:31:43,591 INFO [org.jboss.migration.core.task.ServerMigrationTask#555] (main) Removed persistent deployment from configuration /deployment=cmtool-helloworld4.war
If you are running in non-interactive mode, the JBoss Server Migration tool will migrate all listed deployments.
Migrate Deployment Overlays
The migration of deployment overlays is a fully automated process, the migration tool will search for deployment overlays referenced in the domain configuration, and migrates all that are linked to deployments which were migrated.
The migration console/log will list all deployment overlays found, if any, and print a message indicating the migration/removal of each:
04:33:30,053 INFO [org.jboss.migration.core.task.ServerMigrationTask#559] (main) Deployment overlays found: [overlay4, overlay1, overlay2, overlay3]04:33:30,062 INFO [org.jboss.migration.core.task.ServerMigrationTask#559] (main) Migrating deployment overlay 'overlay4', it's linked to deployment cmtool-helloworld2.war04:33:30,098 INFO [org.jboss.migration.core.task.ServerMigrationTask#560] (main) Removed deployment overlay from server group /deployment-overlay=overlay104:33:30,120 INFO [org.jboss.migration.core.task.ServerMigrationTask#560] (main) Removed deployment overlay from server group /deployment-overlay=overlay104:33:30,148 INFO [org.jboss.migration.core.task.ServerMigrationTask#560] (main) Removed deployment overlay from configuration /deployment-overlay=overlay104:33:30,175 INFO [org.jboss.migration.core.task.ServerMigrationTask#561] (main) Removed deployment overlay from server group /deployment-overlay=overlay204:33:30,198 INFO [org.jboss.migration.core.task.ServerMigrationTask#561] (main) Removed deployment overlay from configuration /deployment-overlay=overlay204:33:30,202 INFO [org.jboss.migration.core.task.ServerMigrationTask#559] (main) Migrating deployment overlay 'overlay3', it's linked to deployment cmtool-helloworld2.war
Host Configuration File Migration
The migration of a host configuration file consists of copying the source configuration file to the target server, and then apply the relevant changes for such configuration to work correctly in the target server, and also take advantage of the target’s server’s new functionality:
-
Migrate Referenced Modules
-
Add jmx Subsystem
-
Remove Unsecure Interface
-
Remove Permgen Attributes from JVMs
-
Migrate Compatible Security Realms
Migrate Referenced Modules
A migrated host configuration may reference, i.e. depend on, modules which are not installed in the target server, and in such case(s) the tool automatically migrates the referenced module(s), from the source server. Beyond that, any module that a referenced module depends on, directly or not, and is not installed in the target server, is automatically migrated too.
A module will be migrated when referenced by:
-
a Security Realm configuration, as plug-in(s) module
Whenever a module is migrated, a message indicating the module's id should be printed in the migration console/log, as exampled below:
03:25:31,205 INFO [org.jboss.migration.core.task.ServerMigrationTask#18] (main) Module cmtool.security-realms:main migrated.
It's possible to exclude the migration of specific module(s), by specifying the id(s) in the environment property named modules.excludes.
Add jmx Subsystem
The JBoss EAP 7 default host configurations include a configuration for jmx subsystem, and the tool adds such subsystem configuration to migrated host configurations.
The environment may be configured to skip adding JMX subsystem configuration, by setting environment property named subsystem.jmx.add.skip.
The subsystem and related extension are added without any interaction required by the user. The migration console and logs display the following messages to indicate it was added.
02:30:40,510 INFO [org.jboss.migration.core.ServerMigrationTask#461] (main) Adding JMX subsystem configuration...02:30:40,566 INFO [org.jboss.migration.core.ServerMigrationTask#462] (main) Extension org.jboss.as.jmx added.02:30:40,734 INFO [org.jboss.migration.core.ServerMigrationTask#463] (main) Subsystem config /host=master/subsystem=jmx added.02:30:40,735 INFO [org.jboss.migration.core.ServerMigrationTask#461] (main) JMX subsystem configuration added.
Remove Unsecure Interface
The tool removes the unsecure interface configuration from all host configurations, to match JBoss EAP 7 default configurations.
The configuration changes are fully automated, and the following messages, in the migration console and log(s), indicate that such changes were done as expected:
02:30:41,015 INFO [org.jboss.migration.core.ServerMigrationTask#480] (main) Interface unsecure removed.
The Migration Environment may be configured to skip the Unsecure interface update, by setting environment property named interface.unsecure.remove.skip as true.
