-----------------------------------

             Summary: [Metadata] Kylin4 metadata cannot be directly upgraded to 
Kylin5. After customers migrate the metadata, they still need to rebuild models 
and other components.
                 Key: KYLIN-6001
                 URL: https://issues.apache.org/jira/browse/KYLIN-6001

          Issue Type: Bug
    Affects Versions: 5.0.0
            Reporter: Guoliang Sun


Current method for upgrading from Kylin4 to Kylin5:

script, and then restore the migrated data.  

Issue: 
After restoring the Kylin5 data, the models need to be rebuilt before they can 
be used.
