Problem

I am trying to use vertica copycluster to migrate to a new DR server.

When I attempt this, I receive following error:

$ ./vbr.py --task copycluster --config-file CopyClusterConfigurationFile.ini

Warning: the vbr config parameter 'verticaConfig' has been deprecated, and is now ignored. The vertica.conf settings are always backed up and restored.
