Chaning the owner of mulitple accounts/companies when an employee is replaced by another

One employee was terminated and is being replaced by a new hire.  Is there a way to replace the new hire's name as the account/company owner on all of the previous employees accounts without having to do each one individually (which is crazy time consuming)?

Thanks,

Christy
