How to migrate existing cli scripts for messagingfrom EAP 6 to use in EAP 7?

Issue

• The following CLI command is failing in EAP 7:

[standalone@localhost:9990 /] ./subsystem=messaging:add()
{
    "outcome" => "failed",
    "failure-description" => "WFLYCTL0030: No resource definition is registered for address [(\"subsystem\" => \"messaging\")]",
    "rolled-back" => true
}

• Also there is another trouble with creating connection factories using below command:

./connection-factory=InVmConnectionFactory:add(connector={in-vm=in-vm},entries=[java:/ConnectionFactory])
