Not able to start the process after BPMN version upgrade

Hello,

I upgraded BPMN version from 7.13.0 to 7.14.0 and now when I start my spring boot app I get the following exception. Can someone please help?

What steps did you follow as part of the migration?

Vinaya_Nayak · May 4, 2021, 11:42am

I was not aware of the steps, I updated version in pom, then my tests failed because of the missing column batch_id_ in ACT_RU_VARIABLE table. I added the column and tried starting again.

Please let me know if there is a guide for the version upgrade.

Niall · May 4, 2021, 11:45am

The upgrade guide can be found here on the docs. There are some addions things to consider as well like if you’re using spring boot ensure the version of spring boot matches with the version of camunda you’re using.
