###  This script converts a pre-existing CMS 6.2 ldif data        ###
###  file (e. g. - created via a utility such as db2ldif)         ###
###  into a normalized CMS 6.2 ldif text file.                    ###
###                                                               ###
###  This subsequent normalized CMS 6.2 ldif text file            ###
###  can be migrated into CMS 6.2 or later utilizing              ###
###  the corresponding TxtTo<Target CMS Version> script which     ###
###  converts this normalized CMS 6.2 ldif text file into         ###
###  a <Target CMS Version> ldif data file.                       ###
###                                                               ###
###  This <Target CMS Version> ldif data file can then be         ###
###  imported into the internal database of the desired CMS       ###
###  server using a utility such as ldif2db.                      ###
###                                                               ###

###  SERVER_ROOT - fully qualified path of the location of the server

###
###  INSTANCE  - if the CMS instance directory is called 'cert-ca',
###              set the CMS instance to 'ca'
###
###              NOTE:  When a single SERVER_ROOT contains more than
###                     one CMS instance, this script must be run multiple
###                     times.  To do this, there is only a need to change
###                     the INSTANCE parameter.
