###  This script converts a pre-existing CS 7.3 ldif data         ###
###  file (e. g. - created via a utility such as db2ldif)         ###
###  into a normalized CS 7.3 ldif text file.                     ###

###  This subsequent normalized CS 7.3 ldif text file             ###
###  can be migrated into CS 7.3 or later utilizing               ###
###  the corresponding TxtTo<Target CS Version> script which      ###
###  converts this normalized CS 7.3 ldif text file into          ###
###  a <Target CS Version> ldif data file.                        ###

###  This <Target CS Version> ldif data file can then be          ###
###  imported into the internal database of the desired CS        ###
###  server using a utility such as ldif2db.                      ###
