ZooKeeper Migrator

You can use the NiFi ZooKeeper Migrator to perform the following tasks:

  • Moving ZooKeeper information from one ZooKeeper cluster to another

  • Migrating ZooKeeper node ownership

For example, you may want to use the ZooKeeper Migrator when you are:

  • Upgrading from NiFi 0.x to NiFi 1.x in which embedded ZooKeepers are used

  • Migrating from an embedded ZooKeeper in NiFi 0.x or 1.x to an external ZooKeeper

  • Upgrading from NiFi 0.x with an external ZooKeeper to NiFi 1.x with the same external ZooKeeper

  • Migrating from an external ZooKeeper to an embedded ZooKeeper in NiFi 1.x

The NiFi ZooKeeper Migrator is part of the NiFi Toolkit and is downloaded separately from the Apache NiFi download page.
