h1. Introduction

When a topology is declared as [dynamic|Topology Configuration], several operating tasks can be done to modify the topology:
* move a running container from a sub-domain to another sub-domain,
* detach a running container from its current sub-domain.

h1. Moving a container

Both a container of an autonomous topology and a container member of a more complex topology can be attached to another existing topology.

The attachment is realized through the JMX API of the container to move using the method '{{attachContainerTo}}' of the MBean '{{Topology}}' with the following parameters:

h1. Detaching a container

Any container member of a dynamic sub-domain can be hot-detached at any moment. After detachment, the container is running in a dedicated standalone topology, ie. in a dedicated sub-domain of a dedicated domain.

The detachment is realized through the JMX API of the container to detach using the method '{{detachContainer}}' of the MBean '{{Topology}}'.
After the detachment, the endpoints of the container are no more available in the initial topology. They are moved in the new one.
