You can use the same databases that you used for the ESB profile of WSO2 EI 6.5.0 with WSO2 EI 6.6.0. However, you need to first remove instances of Scheduled Tasks and Message Processor tasks Processing Tasks that were stored in the registry database from WSO2 EI 6.5.0.


WSO2 EI 6.6.0 requires Tasks to be stored in the registry using a new naming convention. For message processor tasks, the naming convention has changed from TASK_PREFIX + messageProcessorName + taskNumber to TASK_PREFIX + messageProcessorName + SYMBOL_UNDERSCORE + taskNumber. When you run the following migration client, the existing Task references in the registry will be removed. Later in this migration guide, when you migrate the integration artifacts from your EI 6.5.0 instance to EI 6.6.0, new records will be created in the registry with the new naming convention.
