# the changes necessary to bring the environment up to the latest version.

# add a new Up function. This function expects two parameters as folows:
#
# INFRAME - local variable used to idenityf the infrastructure name.
#           This value is stored in the DB as row key
#
# LATESTVERSION - local vaiable used to identify the latest version held
#                 in this script. This needs to be manually updated
#                 each time a new version Up method is created
