An orchestration layer ready for agents, people, and systems — not another legacy BPMS
Your legacy BPMS was built for forms, queues, and a process world that did not include AI. Today’s processes coordinate agents, microservices, SaaS, and humans across systems your suite was never designed to reach. Camunda is the open, agent-ready orchestration platform enterprise architects use to retire proprietary BPM suites without recreating the lock-in they are escaping.
Not a broken BPMS — a process landscape that moved past it
The platform you bought a decade ago coordinates work through forms, queues, and a proprietary engine. It still runs. But the processes your business depends on have moved past it. Loan decisions involve AI agents triaging applications. Claims span twelve cloud APIs and three data warehouses. Onboarding waits on signatures, KYC checks, and compliance reviews that span days.
Your BPMS sees a fraction of any of it. Everything else lives in custom code, RPA bots, point-to-point integrations, and Slack threads. The hidden cost isn’t the license. It’s the architectural drag: every new system gets wired around the BPMS, every model upgrade triggers a migration project, and every regulatory change becomes a six-week scoping exercise.
- A proprietary execution engineThat nobody outside the platform team can read, version, or extend.
- Forms and UIs locked to the suiteWith UX limits set by what the vendor shipped a decade ago.
- Bolt-on AI featuresTied to one model, one pricing scheme, one roadmap.
- Migration costs every refresh cycleBecause the process logic isn’t portable.
None of this is your differentiator. All of it is on your roadmap.
What does replacing a legacy BPMS mean?
Replacing a legacy BPMS today means moving from a closed automation suite to an open orchestration layer that coordinates AI agents, microservices, SaaS systems, and human work in one model. The right destination is built on open standards (BPMN), runs on a distributed engine, and treats agents as first-class participants under the same governance as everything else in the process.
Camunda is that orchestration layer. Process logic stays portable. Agents stay swappable. Audit trails are captured automatically. The same model your engineers commit to git is what business owners review, operators monitor, and compliance audits.
Key takeaways
- Agent-ready by design: orchestrate any AI model or framework without rebuilding the underlying process.
- Staged migration lets you run Camunda alongside your existing BPMS with no big-bang cutover and no drained queues.
- Zeebe scales horizontally to millions of tasks per week with no central database bottleneck.
- Every process instance captures a complete audit trail automatically. Compliance is built in, not bolted on.
Processes designed before AI existed
If your replacement target only does what your current BPMS does, you are refactoring in place. The processes themselves still need reimagining: where agents take over from humans, where deterministic flow takes over from ad-hoc work, where exceptions deserve judgment rather than escalation.
Camunda is built for that re-engineering. Deterministic steps for the predictable majority. Agents for cases that need reasoning. Humans where regulation or risk demands it. All in one model, on one runtime, with one audit trail. This is what makes a BPMS replacement a strategic move rather than a like-for-like swap.
“Every process in your enterprise is legacy. It was designed for a world where AI did not exist. This is why we are now entering the decade of the great re-engineering.”— Jakob Freund, CEO, Camunda
One process model, every pattern you need
Camunda gives enterprise architects a composable foundation that handles the patterns a modern BPMS replacement demands: deterministic flow, agent reasoning, human tasks, long-running state, and integration into the systems you already depend on.
BPMN at the core, never proprietary
Process logic runs on ISO/IEC 19510. Portable across any compliant tool, any compliant runtime, forever. No serialization rebuild when you change vendors.
Zeebe scales horizontally
Peer-to-peer broker cluster, no central database, no single point of failure. Tier-one banks run millions of tasks per week and 300+ transactions per second on this architecture, in production since 2015.
Orchestrate any agent or model
Agents from any framework. Models from any provider. MCP and A2A protocol support. Swap models, change prompts, redeploy without touching process logic.
Long-running by default
Processes wait days, weeks, or months for documents, signatures, or external events. State persists, timers fire, audit stays intact across every pause and resume.
Approvals and exceptions, first-class
Tasklist, native forms, role-based assignment, escalation, and override. Not a custom UI bolted on top. Operators see the same diagram architects model.
Built for migration, not greenfield
Pre-built connectors for SAP, Salesforce, ServiceNow, Kafka, S3, the major LLMs, and any system reachable via REST or gRPC. The systems your legacy BPMS connects to are already here.
Lock-in replaced with portability
A legacy BPMS extracts ongoing migration revenue precisely because its format, engine, and ecosystem are proprietary. Composable architecture inverts that. Each layer is replaceable; each layer holds value on its own.
| Where you are today | Where Camunda fits |
|---|---|
| Proprietary process format. Migration projects every time the tool changes. | BPMN open standard. Process logic reads in any compliant tool, runs on any compliant engine. |
| One AI track bolted on. Tied to one model, one vendor’s roadmap. | Agent-agnostic. Orchestrate any agent or model. Swap when something better ships. |
| Closed connector ecosystem. New integrations require vendor SOWs. | Open SDK and a public marketplace. SAP, Salesforce, ServiceNow, plus REST, gRPC, and Kafka native. |
| Single-vendor stack. Storage, UI, engine, AI all locked together. | Composable. Run on your Kubernetes or our SaaS. Swap any layer without rebuilding the others. |
| Audit trail reconstructed from logs after the fact. | Every process instance captures decision history, agent actions, and human approvals automatically. |
A staged migration, not a single cutover
Most enterprises retiring a legacy BPMS run Camunda alongside the incumbent, route the highest-value processes first, and progressively decommission the old engine as new processes prove out.
Stand up Camunda for one high-impact process
Loan origination, claims intake, employee onboarding. Something with measurable cycle time, clear ROI, and stakeholders who feel the current pain. The first process is the reference architecture for everything that follows.
Add agents where exceptions used to require people
Standard cases keep flowing through deterministic steps. Cases that needed human judgment get an agent that recommends, with humans approving where regulation or risk requires it. The deterministic-versus-dynamic boundary stays under your control.
Migrate adjacent processes onto the same model
Each new process inherits the connectors, governance, and observability already proven by the first. A platform team owns shared capability; domain teams own their workflows. The pattern NORD/LB has run since establishing its Workflow Automation Center of Excellence.
Decommission the legacy engine in stages
Each retired process recovers license cost and removes a maintenance burden. Camunda’s instance migration moves in-flight cases to new versions deliberately, at the granularity you choose. No big-bang releases, no drained queues, no maintenance windows.
Named customers, verified outcomes
to replace a legacy system from design through build, test, and production readiness.
Rabobank →order-level audit visibility after transitioning from legacy platforms. Process redundancy eliminated. Workflows adapt to changing business needs without engineering rework.
First American →decrease in process exceptions since the Center of Excellence launched. 75% of ~4,000 monthly physical letters now fully automated; the remaining 25% routed by an AI agent inside the same orchestrated process.
NORD/LB →Modeled by architects, visible to operators
A legacy BPMS replacement isn’t an IT project. It’s an opportunity to fix the things business owners have been raising for years: cycle times measured in days, exceptions that disappear into queues, no real-time view of what’s actually running.
Camunda exposes every running process to operators using the diagram architects modeled. Which instances are stuck. Which are approaching SLAs. Where bottlenecks form. One source of truth from design through production.
“Camunda has empowered us to build a scalable workflow based messaging system for our customers, making it easy for us to run millions of process instances at any given time. The fact that it supports the existing BPMN 2.0 standard is a wonderful addition.”— Vamsi Krishna, Director of Engineering, athenahealthRead the case study →
Frequently asked questions
What does it mean to replace a legacy BPMS in 2026?
Replacing a legacy BPMS today means moving from a closed automation suite to an open orchestration layer that coordinates AI agents, microservices, SaaS systems, and human work in one model. The right destination is built on open standards (BPMN), runs on a distributed engine, and treats AI agents as first-class participants under the same governance as everything else in the process. It’s a strategic re-engineering, not a like-for-like swap.
How is Camunda different from another BPM suite?
Camunda is an orchestration platform, not a closed automation suite. Process logic is BPMN, an open ISO standard. The engine, Zeebe, is distributed with no central database. Agents from any framework or model provider can be orchestrated. Connectors are open and extensible. Process portability and agent portability are the design goal, not migration revenue. Camunda was named a Visionary in the 2025 Gartner Magic Quadrant for Business Orchestration and Automation Technologies.
Can Camunda run alongside our existing BPMS during migration?
Yes. Most enterprises run Camunda in parallel with the incumbent BPMS, route the highest-value processes first, and progressively decommission the legacy engine. Camunda integrates with the same systems your current BPMS connects to (SAP, Salesforce, ServiceNow, mainframes, custom services), so cutover is incremental rather than a single big-bang release.
Will our existing BPMN models work in Camunda?
BPMN 2.0 is portable by design. Diagrams from any compliant tool import into the Camunda Modeler and execute on Zeebe. Vendor-specific extensions need to be replaced with their open-standard equivalents, which is typically a fraction of the effort of rebuilding from scratch. For non-BPMN process definitions, Camunda’s professional services and partner network have well-rehearsed migration patterns.
How does Camunda support compliance during and after migration?
Every process instance captures a complete audit trail automatically: which path was taken, which decisions were made, which agents acted, which humans approved. Camunda is used in financial services, healthcare, insurance, and government under EU AI Act, HIPAA, BCBS 239, and similar frameworks without custom audit instrumentation. NORD/LB runs banking processes under German and EU financial regulation; First American runs title and order workflows with full audit visibility.
What is a realistic timeline for retiring a legacy BPMS?
Most enterprise architects target a multi-year, process-by-process migration rather than a single cutover. Rabobank reports replacing a legacy system from design through production readiness in 10 weeks. The first new process typically runs in weeks, not quarters, and each retired legacy process recovers license, support, and integration costs, which compounds the business case as the migration proceeds.
