Blink also offers a user interface option to do the same which is, just as Jeffrey suggests, simply exporting the machine.xml file which saves the user's changes to options, rules, and individual module status. This can be accomplished from the Blink menu as follows:
To export:
1) File -> Export -> Export Active Ruleset ...
2) Provide an arbitrary name and save to desired location.
To import:
1) File -> Import
2) Select the XML file exported earlier
Of course it can also be accomplished just as Jeffrey suggests; however, the benefit to doing it through the GUI is that Blink does not need to be shutdown entirely as the files are read in during the import.
