Subject Re: migrate state for local to cluster transition
Date Tue, 07 May 2019 17:02:26 GMT
Hello Ben,

In NiFi Toolkit, the Zookeeper Migrator exists to move state from one ZK
quorum to another, but to my knowledge, there's no local-to-cluster
migrator.  There is a JIRA [1] for this functionality, but it's currently
unassigned, and I haven't heard about any work being done for it.
