Has anyone ran into this problem and simply changed the username? Fortunately this was a hosted domain from my other server and the client hadn't uploaded anything yet or created any email accounts so I figured it would be a good domain to practice on.
The next thing I'm wrestling with is moving the rest of the domains. I have full site backups done with cPanel and downloaded them to my computer. Now I have to learn where to upload them so when they extract they populate properly.
WHM has a transfer tool but I don't think it would be a good idea to use it considering the other server is rather outdated, still running CentOS 5.11 and the new server I have CentOS 7.3 on it.
You can change the username, it will not affect the account especially when it doesn't have big database, however it's not recommended, but WHM recommend to rename the account with same or shorter character length. you can know more from cPanel Documentation.
Please note that when you change a username of an account that host database, you'll need to update database information on config file of web applications running on this cpanel account.
You can use WHM transfer tool, it's a reliable tool. In case you've backups on your PC, you need to upload them to /home to let WHM find them during restoration process.
