Subject: [PATCH] [ENSCORESW-576]. Prevent optimisation of DBs when copying
from staging.
The production and web teams have reported odd going ons when people copy from
staging onto another server. This is because this script optimises databases
before copying. These DBs should already be optimised so there is no need
to do this stage. In fact it can alter the checksums of the MYI files which
causes the webteam to wonder if data has been switched out without them knowing.
