Apache NiFi 2.0.0 includes the removal of multiple deprecated extension components and legacy product features. Version 1.18.0 and following introduced deprecation logging to provide runtime warnings for elements targeted for removal. Upgrading to the latest version 1 release provides the most accurate set of deprecation warnings.
Manual Configuration changes must be completed prior to upgrading from version 1 to avoid breaking changesfailures. Application settings and flow design changes should be completed and tested before upgrading.
Migrating from deprecated components and features requires different steps depending on configured properties. The level of difficulty varies based on the number of properties to be changed and the steps involved to maintain similar behavior.
Processors
Migrating deprecated Processors and properties requires flow design changes. The steps required range from setting different property values to replacing one Processor with one or more Processors providing similar capabilities.
