Hi Ali, You can upgrade between NiFi 0.6 and 1.0 (although we’d recommend you go to 1.1.0 which was just released this week and had 265 issues fixed / features added since 1.0). Follow the migration guide [1], as there are substantial changes introduced in the 1.x versions which you should be aware of. Some of the biggest are the new multi tenant authorization model [2] and the zero master cluster model. As you were not using clustering in 0.x, you do not need to worry about ZMC as it will work by default. There is a capability [3] to migrate the existing “legacy” authorized-users.xml to users.xml and authorizations.xml, which support the new model.
I’d recommend upgrading your standalone node first and once you’re comfortable with the new UI and that you have configured the flow and user access policies the way you want, then spread to a cluster. The flows will migrate with very little interaction (some processors require that they run only on the primary node for synchronization issues, like ListFile, but this is documented in the processor info) and most flows are the same on standalone instances as they are on clusters.
