Operation to migrate from the legacy messaging subsystem to the new messaging-activemq subsystem.
This operation must be performed when the server is in admin-only mode.
Internally, the operation:
- query the description of all the messaging subsystem by invoking the :describe operation.
This returns a list of :add operations for each messaging resources.
- :add the new org.widlfy.extension.messaging-activemq extension
- for each messaging resources, transform the :add operations to add the
corresponding resource to the new messaging-activemq subsystem.
In this step, changes to the resources model are taken into account
(e.g. cluster-connection's connector-ref is named connector-name in the new messaging-activemq subsystem.)
- :remove the messaging subsystem
The companion
:describe-migration
operation will return a list of all the actual operations that would be
performed during the invocation of the
:migrate
operation.
