Your streaming platform shouldn’t decide your roadmap

Most migrations start with one of four questions.

Who controls our data?

Managed Kafka from a US vendor or hyperscaler puts a foreign supplier in your critical path. Axual runs where your data must stay, under your operational control.

Why does the bill keep growing?

Usage-based pricing grows with every topic, partition and byte. Axual pricing is set by deployment model, support level and scale, so costs stay predictable.

What if we need to leave?

Proprietary features make exit expensive. Axual is built on standard Apache Kafka and Strimzi, so your applications keep using standard Kafka clients, on Axual and on whatever comes next.

Can we prove it to the regulator?

DORA requires financial entities to have exit strategies for critical ICT providers. A tested migration path to a European platform turns your exit plan from a document into something you can execute.

Both platforms run side by side until you’re ready

Axual Distributor replicates messages, schemas and consumer offsets from your current cluster to Axual. Your applications keep running on the old cluster while the new one stays in sync. You then move producers and consumers across in phases, one application or one team at a time. Because offsets are synchronised, consumers pick up exactly where they left off. If something doesn’t behave as expected, you switch back.

Everything in sync

Messages, schemas and offsets replicate continuously

Move per application

No single cutover moment for the whole infrastructure

Rollback at every step

The old environment stays live until you decide it’s done

From assessment to handover in 5 steps

Assessment

We review your current Kafka environment, including topics, retention, and configuration.

Planning

We agree on the right migration approach for your situation and timeline.

Migration

We execute the move, with both environments running in parallel until cutover.

Validation

We confirm data integrity and application behavior on the new environment.

Handover

Your team gets a full record of what changed, plus training on anything new.

Land in an environment that’s cleaner than the one you left

Access reviewed, not copied

Roles and permissions are reviewed and reset during the move instead of carried over by default, so old access debt stays behind

Encrypted throughout

Data is encrypted in transit between environments, not only at rest

An audit trail for compliance

A complete log of what migrated, when and how, ready for your auditors

Governance from day one

Every topic has an owner, and every application needs approved access before it can produce or consume

Proven in regulated, mission-critical environments

PTSB, Logius and PostNL run business-critical event streaming on Axual

PTSB

Frequently asked questions

What counts as a Kafka migration?

Any move of Kafka workloads from one environment to another: from Confluent or MSK to Axual, from a self-managed or Strimzi cluster, between cloud providers, or between regions. In every case, data, schemas and consumer positions need to transfer correctly.

Can a Kafka migration really happen with zero downtime?

Yes. Instead of one cutover moment, both environments run in parallel while Distributor keeps messages, schemas and offsets in sync. Applications move across in phases, and producers and consumers keep running throughout.

What are common mistakes in a Kafka migration?

Most problems come from planning, not from the move itself: migrating unused topics or misconfigured retention, underestimating testing time, or having no rollback plan. The assessment phase is designed to catch these early.

How long does a migration take?

It depends on the number of topics, applications and teams involved. A single-cluster migration can take weeks, while large multi-team infrastructure move in phases over months to a year. The assessment gives you a realistic timeline before anything moves.

Do you migrate from any Kafka setup, or only specific ones?

We support migrations from self-managed and DIY Kafka setups, other managed Kafka platforms, and between cloud providers or regions. The right approach depends on your starting point, which is why every migration starts with an environment assessment.

Is our data secure during the migration itself?

Yes. Data is encrypted in transit throughout the migration, and access controls are reviewed and reset as part of the move instead of carried over by default.

What do we get once the migration is complete?

You get a validated environment, a full audit trail and a handover with training for your team. If you continue with Axual Platform Support, the same team carries straight through into ongoing operations.

How is a migration priced?

Every migration starts with an assessment scoped to your environment. After that, you receive a quote for the migration itself, based on its size and approach.
