@Venkoff, you can delete the token.tkn in the C:\Users\(your user)\.TRIGGERcmdData folder then restart the agent. It will prompt for the token again, and create the computer in the new account if you use a token from the new account's Instructions page.
I recommend you backup your commands in your C:\Users\(your user)\.TRIGGERcmdData\commands.json file while you're there.
