Who Provides Extended Support for Apache NiFi 1.x After NiFi 2.0?

The short answer

Two providers publish ongoing security fixes for NiFi 1.x. Cloudera supports Cloudera Flow Management 2.1.7, which ships its own NiFi 1.28.1 builds, until September 2027, for customers running Cloudera's distribution. OSSeva ships patched builds of Apache NiFi 1.19, 1.23, 1.26 and 1.28, including the bundled Jetty and Spring libraries the NiFi project says it cannot upgrade on 1.x. Perforce OpenLogic sells NiFi support without patched builds.

If you run Apache's own NiFi 1.x binaries, Cloudera's support does not reach them unless you move to its distribution. That is the main question to settle before comparing anything else.

Where Apache NiFi 1.x stands

The NiFi download page states that 1.28 is the last minor release of the 1.x series, with an end of support date of 8 December 2024. The project may consider critical framework fixes "on an exceptional basis", but those fixes do not include dependency upgrades, and the page names Jetty 9.4, Spring Framework 5.3 and AngularJS 1.8 as dependencies that cannot be upgraded on 1.x.

NiFi 2 needs Java 21, replaces flow.xml.gz with flow.json.gz and removes a long list of deprecated components, and an upgrade must pass through 1.27 first. The NiFi end-of-life chart tracks every line, and NiFi vulnerabilities by version shows what reaches 1.x.

Apache NiFi support providers compared

Each row reflects what the provider publishes on its own site as of 6 October 2026.

Cloudera's dates are the longest published for NiFi 1.x, and they cover Cloudera's builds, not Apache's. Openflow is in the table because Snowflake acquired Datavolo, a company built around Apache NiFi, and the question of whether Datavolo still sells NiFi support comes up often. Datavolo's site now carries the acquisition notice, and Snowflake's NiFi-based product is Openflow, a destination for flows rather than support for the clusters you run today.

How the providers differ

Cloudera

Cloudera is the clear choice if you already run Cloudera Flow Management or can move to it. Its 2.1.7 service packs ship Cloudera builds of NiFi 1.28.1, supported until September 2027, and its 4.x releases give a supported NiFi 2 path into 2029. Earlier CFM 2.1.5 and 2.1.6 releases ended in August 2025. In the cloud, Cloudera Data Flow supports each NiFi runtime for 18 months, so its 1.28.1 runtimes also end in September 2027. If your NiFi sits next to older CDH or HDP clusters, CDH and HDP end of life covers that side.

Perforce OpenLogic

OpenLogic lists NiFi among more than 400 supported technologies at all three support levels. It suits a team that wants one contract for help running NiFi alongside the rest of its stack. It does not publish patched NiFi 1.x builds. See OSSeva vs OpenLogic.

OSSeva

OSSeva for Apache NiFi patches the 1.x line in place, so flow.xml.gz, the NAR set, parameter contexts and controller services stay as configured. That covers NiFi's own authentication and authorisation code and the libraries inside the NARs, where most NiFi advisories land. OSSeva matches the exact binaries you run, whether Apache's or Cloudera-packaged. Assure adds a processor and controller service inventory, a gap analysis against what NiFi 2 removed, a credential handling audit and a costed migration plan; Operate adds 24/7 backpressure and throughput monitoring, a 15-minute P1 response and execution of the flow migration. Pricing is per cluster, not per flow or data volume.

How to choose

Our NiFi 1.x to 2.0 upgrade guide covers the sequence and the inventory step, and NiFi 1.x end-of-life dataflows covers running extended support during the move.

Where OSSeva fits

OSSeva covers Apache NiFi 1.x for estates that are not on Cloudera's distribution, or that are behind Cloudera's own lines, with signed builds and a migration plan built from a real processor inventory. See the extended support vendor roundup for how OSSeva compares across other technologies.

Frequently asked questions

Who provides extended support for Apache NiFi 1.x?

Cloudera supports its own NiFi 1.28.1 builds in Cloudera Flow Management 2.1.7 and Cloudera Data Flow until September 2027. OSSeva ships patched Apache NiFi 1.19, 1.23, 1.26 and 1.28 builds. OpenLogic offers general NiFi support without patched 1.x builds.

Is Apache NiFi 1.x still supported?

Not by Apache. The download page gives 1.28's end of support as 8 December 2024, and 1.28.1 was the last release. The project may make exceptional critical fixes, but says those will not include dependency upgrades.

Does Cloudera support Apache NiFi 1.x?

Cloudera supports its own NiFi distribution. CFM 2.1.7, based on NiFi 1.28.1 in its latest service packs, is supported until September 2027. Apache binaries outside that distribution are not covered.

What happened to Datavolo NiFi support?

Snowflake acquired Datavolo, and Datavolo's site now carries that announcement. Snowflake's NiFi-based product is Openflow, a managed integration service. It does not publish a support offer for self-managed NiFi 1.x clusters.

Can we upgrade straight from NiFi 1.x to 2.0?

Only from 1.27.0 or later, per NiFi's migration guidance. Clusters on 1.19 or 1.23 move to 1.27 or 1.28 first, replace removed components there, and then move to 2.x on Java 21.
