Hi we are trying to migrate from activiti 6.0 to camunda 7. The workflow seems to be running while using Camunda’s internal h2 database, but we are facing errors while setting it up to connect with our database, particularly a schema in our database.
This is the error that we are facing-
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: There is already an object named 'ACT_GE_PROPERTY' in the database.
