I found this helpful (including the comments):

http://www.cyberciti.biz/faq/howto-change-rename-user-name-id/

I had to do this just as few days ago while setting up a system. I had
set it up to use don and found out the user uses donny. I left the home
directory as don, but changed the rest to donny. Given that it is a new
install there wasn't much in the way of apps that depended too heavily
on 'don' vs 'donny'.

I did not try:

killall -u old
id old
usermod -l new old
groupmod -n new old
usermod -d /home/new -m new
usermod -c “New Real Name” new
id new

but suppose I still could as I'm still messing around with the system &
don't have to deliver it until sometime next week.
