-dstConfig	true	Required] The KylinConfig of the target cluster with 3 kinds of format: 1. uri e.g. user:pwd@host:port. 2. properties file e.g. /home/kylin/conf/kylin.properties 3. local metadata dir e.g. /home/kylin/meta_backups/meta_2021_04_21_18_29_04
-allCubes	false	[Optional] Migrate all cubes in source cluster.
-cube	true	[Optional] migrate single cube in source cluster, argument value is the cube name to migrate.
-srcProject	true	[Optional] migrate all cubes under specific project in source cluster, argument value is the project name to migrate.
-dstProject	true	[Optional] cube's new project home(will be created if not exists). If not set, keep the same as cube's original project. With this option, we can migrate a "single cube", "a project" or "all cubes" to target cluster.
-migrateSegment	false	[Optional] migrate segment data

Please note:

The URI format of KylinConfig is not backward compatible, for it fetches metadata storage information by http request, older version may not be supported.
only one of "-cube", "-srcProject", "-allCubes" could only be present to specify metadata to migrate.
CubeMigrationCli will reload target cluster's metadata, we don't have to restart target cluster.
