> We have users of Artemis 1.x that uses the transformer interface defined in org.apache.activemq.artemis.core.server.cluster.Transformer.
>  
> This class was moved in Artemis 2.x in an incompatible way: [https://github.com/apache/activemq-artemis/blob/master/artemis-server/src/main/java/org/apache/activemq/artemis/core/server/cluster/Transformer.java] that redirects to [https://github.com/apache/activemq-artemis/blob/master/artemis-server/src/main/java/org/apache/activemq/artemis/core/server/transformer/Transformer.java]
> We are updating Artemis 2.x but it breaks the client configuration that was using the old interface.
> We have strong requirement for backwards compatibility and we'd like to come up with a solution so that the new interface could be made backwards compatible with the existing one.
> Would it be possible sense to reintroduce the old interface in the server.cluster package so that old code would still be able to run with Artemis 2.x?
