> Create a self service interface for cube migration
> --------------------------------------------------
>
> Key: KYLIN-4485
> URL: https://issues.apache.org/jira/browse/KYLIN-4485
> Project: Kylin
> Issue Type: New Feature
> Components: Tools, Build and Test
> Reporter: Zhong Yanghong
> Assignee: Zhong Yanghong
> Priority: Major
> Fix For: v3.1.0
>
> Attachments: cube-migration-new.png, cube-migration-old.png
>
>
> Current cube migration process is as follows:
> !cube-migration-old.png!
> There're a few drawbacks:
> * kylin admin has to manually check all related aspects to decide whether a
> cube is good for migration. If cube design is not good, there'll be many
> interaction between users & kylin admins
> * kylin admin has to login to the backend server and then run a command to
> do the migration, which is tricky and easy to make mistakes
> * there's little compatibility check between source metadata & destination
> cluster.
> A self service interface will refine the migration process as follows:
> !cube-migration-new.png!
> We can see with the new migration process, there'll be few interactions
> between users & kylin admins and much less work for kylin admins.
>
> *For this new feature, add some new properties*:
