'CubeMigrationCLI.java' CLI used positional arguments before, and is now changed to POSIX Style arguments, look at the following example:

Code Block
languagebash
themeMidnight
./bin/kylin.sh org.apache.kylin.tool.CubeMigrationCLI -srcConfig ADMIN:KYLIN@host1:7070 -dstConfig ADMIN:KYLIN@host2:7070 -overwriteIfExists -srcProject default

...

1.Export metadata from older cluster to local dir using scripts in old software package:

Code Block
languagebash
themeMidnight
./bin/metastore.sh backup

2. Use 'CubeMigrationCLI.java' CLI provided in 4.0 package to set source KylinConfig to metadata directory exported in step 1

Code Block
languagebash
themeMidnight
./bin/kylin.sh org.apache.kylin.tool.CubeMigrationCLI -srcConfig ${exported_metadata_dir} ...

'CubeMigrationCLI.java' CLI will read exported metadata and change cube's information, including 'storage_type', 'query_engine', 'version' and 'cube signature', and then write to into target metadata storage.
