Re: [wildfly-dev] Management operation for legacy subsystem migration

Conversion between subsystems is fairy staightforward as they are very similiar. The
problem is that the jacorb subsystem, from which :migrate operation is executed, has also
a compatibility subsystem role. What is more it behaves differently in standalone and
domain mode. Standalone subsystem emulates jacorb and as a result of that it checks that
all properties can be emulated - it they can't the server won't start. On the
other hand domain controller does not reject properties as it may send them to hosts with
jacorb subsystem. So migrate operation in standalone mode works the way Jeff describe it
but the "rinse and repeat" stage is moved to server startup.
We could consider being more forgiving in admin-only mode; instead of
failing, log ERROR messages. That gives the user the option to fix stuff.
It would be very good to be able to take an AS 7 / WF 8 / EAP 6 config
and be able to bring it into compliance with WF 10 without having to use
anything but the management API.
It has a runtime though. Migrate operation in domain mode requires
discussion. Point 3 does not apply to iiop - no data is moved.
