Hi,
i want to migrate camunda 7.8 to 7.10 because of jdk11 support. Is it possible to migrate running processes while switching the Tomcat version to Tomcat 9? In other words, if I download the latest version of Camunda, connect it to the old database and put all.war files in the Webapps folder, does that work?
You would need to update the database using the provided scripts

Hi,
thanks for the answer. Do i need specific configurations? I am scared, that tomcat deploys the war files on startup and overwrites the old deployments in the database, which would delete the running processes. Is that safe?
Re-deploying the processes shouldn’t affect running instances, it would just create a new version of the process if anything had changed.
Although i would advice that you make a copy of your database and test the migration against the copy first.
Thank you very much for your help.
