Migrate Apache NiFi 1.x to 2.x
with Zero Downtime
Fully tested, zero data loss, and production-ready migration delivered in just 6 to 8 weeks by India’s leading open-source Apache NiFi contributor.
Industries We've Served
Our NiFi Migration Expertise
From legacy cluster assessment to fully modernized cloud-native deployment, our Apache NiFi migration services handle every layer of your migration.
NiFi Cluster Modernization
Multi-platform deployment across On-Premise, Docker, and Kubernetes (EKS, AKS, GKE). We migrate ZooKeeper coordination to native Kubernetes and implement Stateless NiFi with sidecar configurations for cloud-native resilience.
Flow Analysis & Migration
Automated conversion of XML templates to JSON-based flow definitions. We have expertise in full component mapping, replacing deprecated 1.x processors, Variable Registry bulk-converted to Parameter Contexts, and flows standardized via NiFi Registry or GitHub/GitLab.
Seamless Cluster Upgrade
Mandatory stepwise bridge upgrades (1.x -> 1.28.1 -> 2.x) are managed end-to-end. We deliver a scripted conversion of nifi.properties and authorizers.xml with Blue-Green deployment for zero downtime and modern TLS/OIDC/SAML security migration.
Custom Processor & API Migration
Our experts handle NAR refactoring to seamlessly port custom Java code to the Apache NiFi 2.x API, ensuring full compatibility with Java 21 dependencies. We also specialize in Python processor conversion using the Native Python Processor API, backed by automated regression testing to validate all custom extensions.
Enterprise to Open Source Transition
Full vendor decoupling from Cloudera CFM or HDF to pure Apache NiFi environments. We map enterprise-only processors to open-source equivalents, eliminate vendor license fees to reduce TCO, and harden security on the open-source stack.
Upgrade Automation
We perform automated pre-migration scans to detect incompatible components early and minimize risks. Our experts leverage the Apache NiFi Toolkit CLI for bulk flow exports and imports, while implementing CI/CD pipelines to ensure consistent environment promotion with automated smoke tests validating data parity post-migration.

4-Phase Migration Roadmap
A battle-tested methodology delivered by a trusted NiFi migration service provider, covering infrastructure, data flows, automation, and security across every environment.
Assessment & Planning
- Evaluate current state (On-Prem v1.x, legacy Java)
- Plan stepwise transition path (1.x -> 1.28.1 -> 2.x)
- Define target architecture (K8s/AKS/EKS, Java 21)
- Assess legacy security & identify proprietary deps
- Inventory all flows, including undocumented ones
- Review existing operations & manual processes
Preparation & Analysis
- Flow analysis & XML → JSON template transformation
- Pre-migration scanning for incompatible components
- Analyze custom NARs and processor dependencies
- Develop Ansible automation scripts
- Plan CLI orchestration strategy
- Plan security migration to modern TLS/OIDC
Migration & Execution
- Multi-platform deployment to cloud K8s
- Cluster version migration to v2.x
- Blue-Green zero-downtime deployment

The Only Indian Open Source NiFi Contributor
Our deep contribution to Apache NiFi core codebase gives us an unmatched understanding of the upgrade path, enabling a seamless upgrade to Apache NiFi 2.x from internals to enterprise deployments.
Open Source DNA
We actively contribute to Apache NiFi's codebase, giving us first-hand knowledge of 2.x internals, APIs, and breaking changes before they hit production.
Automation-First Approach
Ansible scripts, NiFi Toolkit CLI orchestration, and CI/CD pipelines dramatically reduce manual effort and migration risk across all environments.
Enterprise Security Experts
From legacy SSL to hardened Keycloak with OIDC/SAML, we handle complex SSO migrations without disrupting existing user access or sessions.

Our NiFi Upgrade Package
A fixed-scope package designed to deliver complete, production-ready NiFi 2.x environments from start to finish.
Comprehensive coverage across (Dev/QA/Prod) environments, all migrated and validated.
Migration and optimization of approximately 10+ NiFi data flows, including undocumented flows recovered and standardized via NiFi Registry.
Typical engagement duration is 6 to 8 weeks, depending on complexity, with clear milestones.
We use a parallel-run strategy with automated failover validation, so your data never stops flowing, even during cutover.
