Before migrating from Cloudera Data Science Workbench (CDSW) 1.10.0 or later to
Cloudera Machine Language (CML) in CDP Private Cloud 1.5.0, you must meet a number of
prerequisites to succeed. A prerequisite for migration is installation of CML on your CDSW
cluster.
Migration from CDSW
configured with LDAP, SAML, or LOCAL authentication to CML is supported, but the
automatic migration described in this document is supported only if CDSW is running with
LDAP. The migration process does not automatically migrate your authentication
configurations. The steps below for meeting prerequisites include LDAP set up in CDSW
before migration begins. Later, you follow post-migration instructions to configure LDAP
on CML.
The migration also does not migrate your CDSW endpoint connections. Later,
you follow post-migration instructions to set up LDAP, endpoint connections, and DNS
on CML. Also, you need to download CDSW-related Grafana dashboards, so you can
upload them after migration to CML.
You must have a CDSW 1.10.0 or later cluster in CDP; otherwise, make one of the
following choices.
If you have a CDSW installation in either CDH or HDP, migrate to CDP Private Cloud 1.5.0
or later, and then migrate CDSW to CML.
Enable the CML features during installation that are counterparts to those you
were using in CDSW.
For example, enable model metrics and monitoring.
If you do not enable the same, or similar, CML features during installation
that you were using in CDSW, attempting to use the CML feature later will
fail.
