Migration plan: * add zk* to emergency * copy data files on each node to a safe place for DR backup * make a json data backup: zk-shell localhost:2181 --run-once 'mirror / json://!tmp!zookeeper-backup.json/' * manually run a modified playbook to set up the docker infra without starting containers * rolling restart; for each node: * stop zk * split data and log files and move them to new locations * remove zk packages * start zk containers * remove from emergency; land this change.
