Release : 13.0
Component : CA Harvest Software Change Manager

Started with this list of users:
Then, created a tab-delimited text file with old name and new name for each of the users I wanted to change:
And finally I ran the husrmgr command to process the list:
The easiest way to build the text file is to dump your list of usernames into an excel spreadsheet, add a second column with the new user name, then save that to a tab-delimited text file or just copy the range and paste it into Notepad.
