The method comprises removing the first transaction service device from on-line service and installing new software on the first transaction service device. Next, a current database associated with the second transaction service device is transferred to the first transaction service device. The transferred current database is converted into a format associated with the new software. After the transfer and conversion of the current database, the first transaction service device is returned into on-line service.
