Is it possible to migrate from the previous release? If so, how?
Yes, no specific steps needed unless prior updates to config subsystem modules were made via the controller-config yang-ext mount in which case the etc/opendaylight/current/controller.currentconfig.xml file must be manually edited to remove the following elements corresponding to config yang modules that were removed:
- Remove the <data-broker> element from the <module> element with <name> binding-broker-impl
- Remove the <module> element with <name> inmemory-binding-data-broker
- Remove the <service> element with <name> binding-data-broker
- Remove <capability>urn:opendaylight:params:xml:ns:yang:controller:threadpool?module=threadpool&revision=2013-04-09</capability> from <required-capabilities>
Since the config subsystem is deprecated, it is recommended to migrate any custom configuration additions and/or changes contained in controller.currentconfig.xml and remove the file.
