Upgrade Path for Apache Nifi

Any tips for upgrading an Apache Nifi instance? We were thinking we would do something similar to the following:

  1. Deploy the latest Nifi versions to our running instances.
  2. Deploy any custom NARs to the updated version.
  3. Make sure to drain the existing Nifi instance.
  4. Shutdown current Nifi instances.
  5. Start new Nifi instances

The outline you write should work just fine. You should be able to skip the step about draining the queues. It is designed to simply restore those. Be sure to also copy over any customized content of your previous install conf folder to the new install folder. Most importantly copy over the flow xml. The idea is that you should be able to upgrade within seconds and have the same flow and all data retained. Now, we need to do a much better of job of making that not so much of an exercise to the reader as it is today. We need to help automate that and we need to document the various cases one should consider.

As you work through it feel free to let us know. We can also help at [email protected] but will also try to keep an eye out here.

Thanks Joe
