I’ve covered this tool many times since rebooting this site as The Automation Blog in 2013, and as I often do when I get a question on something I’ve covered previously, I went back to my most recent article on the subject to see if the procedure still worked. Recently one of our readers submitted a question asking for help migrating from a legacy Rockwell PLC (aka PLC-5 or SLC-500) to their new PAC lines (ControlLogix and CompactLogix.) In his email he went on to say he needed help because he didn’t have a copy of the Project Migrator, previously called the Translation tool.
