Nissim Shiman commented on NIFI-9440:
-------------------------------------
As this change touches a wide range of apache nifi core files/functionality,
extensive edge testing was done to verify the integrity of this new
functionality, especially with regards to backward compatibility with flow
configurations from apache nifi 1.16.x where this functionality does not exist.
flow.xml.gz / flow.json.xml from earlier versions can be dropped into the conf
directory and on nifi restart, any controller services in these files will have
tags added to reflect a bulletinLevel at the WARN level (to maintain backward
compatibility where WARN was previously globally set [1])
Templates from previous nifi versions can be used and nifi will start up and
will modify any controller services in these files (and their definitions in
the flow.xml.gz/flow.json.gz) to have a bulletinLevel at the WARN level
nifi-registry (on 1.17 and later) can be updated using flow_storage and
database directories from registries of 1.16.x and controller services in
flows that are brought over will have bulletinLevel set at WARN level. Their
definitions in the flow.xml.gz/flow.json.gz will be gracefully updated to
reflect this. The registry will also remain "up to date" at the latest version
when this done as well.
