One thing you can do is to make a second connection to Redshift then go in Data - Replace Data Source, select Vertica as Current and Redshift as Replacement. After that you can close the Vertica connection.
I only done it once and i still had to do some manual adjustments on the calculated field wich were still referencing to Measures from the first connection, but at least the Dimensions were correctly replaced and i didn't have to rebuild the Visual.
I don't know if there is a better way to make the transfer more transparent...
even I tried this method when i had to change the data source and was able to do that.
