Hi Johnson, Here's some general advice for upgrading your NiFi 1.17 installation. There have been a lot of changes since NiFi 1.17 so you won't be able to jump straight to the latest version.
- NiFi 1.x is no longer maintained so ideally you want to aim to upgrade to NiFi 2. - Because you are on NiFi 1.17 you would need to upgrade to the latest version of NiFi 1 (1.28.0) before you can upgrade to NiFi 2.x. - The NiFi documentation is good, I would suggest starting there -> https://nifi.apache.org/documentation/v1/. The admin guide has some useful information on upgrading your NiFi cluster. - Make sure you back up your NiFi installation before you begin upgrading and test the upgrade in a non-production environment before doing this for real. - There are a lot of features and processors deprecated in NiFi 2, so you will need to make sure that you thoroughly test your workflows.
