QUESTION AND ANSWER
Can an Unattended machine be moved from one account to another?
GoToAssist Remote Support
No. Unattended machines have a specific Unique Identifier which installs in the registry linking them back to a specific account. If a new or different account is necessary, the Unattended machine must be uninstalled and then reinstalled under the new or different account to add the proper Unique Identifier back into the registry of that machine.
