Hi - I performed migration from H2 to PostgreSQL, and ran into a potential bug.
After switching the database config, registry started up fine. But the tables were all empty. On digging a bit deeper, I found that the default H2 database file is named nifi-registry-primary.mv.db. The migration code is looking for a file named nifi-registry.mv.db and hence unable to find it. The log reports 'Did not find legacy database file...' To verify this, I renamed existing H2 file to nifi-registry.mv.db. Upon startup, the file was detected and migration happened properly. I can file a JIRA, but just wanted to make sure I was not missing any config step. Thanks. -- Jagrut
