Issue/Introduction

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.

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
