Camunda 7 to Camunda 8 migration help, one ticket at a time
Assigned to a Camunda 7 to 8 migration and the architecture is new to you? Camunda 8 is not a drop-in upgrade — the engine is remote, the code model is different, and expressions change. An engineer who has worked through these migrations joins you over screen-share and works through each step with you.

What Camunda 7 → 8 migration covers
Code model changes
Moving JavaDelegates and external task handlers to Zeebe job workers, and rethinking logic that relied on the engine running inside your application’s transaction.
Models and expressions
Adjusting BPMN and DMN models for Camunda 8, converting JUEL expressions to FEEL, and handling elements that behave differently.
Operations
From Cockpit to Operate, from embedded engine to a Zeebe cluster, and what changes for incidents, retries and monitoring.
Running both side by side
Strategies teams use while old instances finish on Camunda 7 and new ones start on Camunda 8, and how to test both paths.
Where developers usually get stuck
- A delegate relied on the engine sharing your database transaction, and that no longer holds.
- JUEL expressions fail after conversion and the FEEL equivalent isn’t obvious.
- You need to keep in-flight Camunda 7 instances running while new work starts on Camunda 8.
- Operate shows incidents that never appeared in Cockpit.

What developers say after working with us
Names are shortened to protect our clients’ confidentiality.
“The technical mentoring helped me work through complex Java, Spring Boot, and microservices challenges. The explanations were practical and focused on real-world development, debugging, and production troubleshooting.”
“I needed guidance with Camunda process orchestration, BPMN workflows, external task workers, and Java integration. The structured technical sessions helped me understand workflow implementation and resolve development challenges.”
“The support covered React, Java, Spring Boot, REST APIs, and database integration. The practical approach helped me understand how frontend and backend components work together in an enterprise application.”
“The support covered React, Java, Spring Boot, API integration, and database operations. I especially appreciated the step-by-step explanations and practical examples that helped me troubleshoot full-stack application issues.”
“The sessions focused on Java microservices, exception handling, SQL queries, logs, and debugging production issues. The guidance was structured and focused on understanding the root cause instead of just fixing the immediate problem.”
“I needed guidance across multiple technologies, including Java, Camunda, React, and REST APIs. The integrated approach helped me connect backend workflows with frontend functionality and build a better understanding of the complete application.”
Ground rules that protect you and your job
You stay at the keyboard
You share your screen and do the work; we guide, explain and review. You own your commits — that’s how the skills stick.
Your employer’s systems stay protected
We never ask for passwords or repository access. Please check your employer’s policies allow screen-sharing before you book. We don’t take on export-controlled (ITAR/EAR), classified or health-records work.
Confidential by default
We sign an NDA on request and never share who our clients are or where they work.
One engineer, one context
You won’t have to re-explain your project each time. Your engineer keeps notes on your codebase and goals.
From first call to confident on your own
Free scoping call
30 minutes on your role, stack, team rhythm and where you feel shaky. Share your requirement and we match you with an engineer who knows your stack.
Schedule around your stand-up
Sessions land in your local working hours — Americas, Europe, Middle East or Asia-Pacific — with a slot before stand-up if you want one.
Work through your tickets together
You share your screen and drive. We explain the code, debug with you, and review your changes before you open the PR.
Taper off as you grow
Most engineers move from daily to weekly sessions within a couple of months. The goal is that you no longer need us.

Camunda 7 vs Camunda 8: what actually changes for Java developers
Embedded engine vs Zeebe, JavaDelegates vs job workers, JUEL vs FEEL, Cockpit vs Operate: a practical comparison of Camunda 7 and Camunda 8 for Java developers.
Zeebe job retries and incidents in Camunda 8, explained
Why a Zeebe job keeps retrying, how retries, backoff and timeouts work, when incidents are created, and how to resolve them in Operate — with Java examples.
Is Camunda 8 a simple upgrade from Camunda 7?
No. Camunda 8 runs a remote Zeebe engine instead of an embedded one, replaces JavaDelegates with job workers, and uses FEEL instead of JUEL for expressions. Most migrations involve code, model and operational changes.
Will you do the migration for my team?
No. We support you, the developer assigned to the migration. Over screen-share, your engineer explains each step, debugs with you and reviews your changes.
Can you help if we’re only partway through the migration?
Yes. Many clients join mid-migration with both engines running. Your engineer starts from wherever your team is.
