NiFi Flow Estate Assessment
A written inventory of your process groups, processors, controller services and custom NARs, with what breaks on NiFi 2 and a sequenced plan in engineer-weeks.
NiFi 1 to NiFi 2 Migration
The last 1.x hop, templates turned into versioned flows, scripted components rewritten, removed processors replaced, Java 21, and a tested cutover with rollback.
Flow and Custom Processor Engineering
Record-oriented flows, custom processors in Java or the NiFi 2 Python API, parameter contexts, Registry-backed promotion and secure site-to-site.
Ongoing Flow Operations
Retained senior capacity after cutover: cluster tuning, back-pressure and queue triage, provenance and repository management, upgrades within 2.x.
One technology only
Apache NiFi flow estates are the whole practice, not one tile on a big-data agency menu.
Evidence before production
A component-by-component list of what breaks is written down before anyone touches a production node.
At home in regulated estates
On-prem and air-gapped clusters, access policies, audit trails, change windows and documented cutovers with rollback.
Honest about the destination
If a flow is really a nightly batch job or a commodity SaaS extract, the assessment says retire it rather than migrate it.
