The separator is one of the characters in the IFS variable, which can be modified to suit your needs
Note that you can still pass arguments with embedded separators by single or double quoting them.

prosody-migrator

prosody-migrator(8)													       prosody-migrator(8)

NAME

       prosody-migrator - Migrate data between Prosody data stores

SYNOPSIS

	     prosody-migrator [OPTIONS] [SOURCE_STORE DESTINATION_STORE]

DESCRIPTION

       prosody-migrator is used to move data (user accounts, rosters, vcards, etc.)  between different data stores. For example this allows you to
       migrate data from a file-based store to an SQL database, and vice-versa.

       Note: the migrator assumes that the destination store is empty. Existing data that conflicts with data in the source store  will  be  over-
       written!

OPTIONS

       --config=FILENAME
	      Specify an alternative config file to use. The default is /etc/prosody/migrator.cfg.lua.

       SOURCE_STORE
	      The name of the store (defined in the config file) to migrate data from.	Defaults to 'input'.

       DESTINATION_STORE
	      The name of the store (also defined in the config file) to migrate data to.  Defaults to 'output'.

FILES

       /etc/prosody/migrator.cfg.lua
	      The migrator config file.
