Description

CU is trying to migrate the scheduler data store from 5.9.0.redhat-611442 to 5.11.0.redhat-630371.

These are the relevant logs (full log attached):

2019-06-13 16:20:50,186 | INFO  | AMQ-1-thread-1   | JobSchedulerStoreImpl            | .scheduler.JobSchedulerStoreImpl  314 | 162 - org.apache.activemq.activemq-osgi - 5.11.0.redhat-630371 | Attempting to move old store files from /Users/fvaleri/cases/02403351/data/amq/amq/scheduler to /Users/fvaleri/cases/02403351/data/amq/amq/scheduler/legacySchedulerStore

This is the layout of the scheduler data store before and after the migration:
