# Auto Upgrade and VRSD
### Overview
The Auto Upgrade feature allows a site to initiate a complete software upgrade without requiring the presence or expertise of a technician (VASC) or intervention from the Verifone HelpDesk.
The software is transferred to the system either by using the Auto\_Upgrade.jar program or by an automated remote software download. Verifone Remote Software Download (VRSD) is the name for Verifone's implementation of the automated remote software download.

*If a site is upgrading from release 53.26 or lower to release 55.02 and higher, it is recommended to use the following instructions instead of the Package Sender (Auto\_Upgrade.jar):*
* *Back up the site data using the SMS Import/Export Utility.*
* *Perform a manual reload using the Petro Suite Installer.*
* *Restore the site data using the SMS Import/Export Utility.*
*The alternative software loading methods are VRSD and USB. See the Verifone Commander and POS Software Installation Guides for more details.*

*Updates to Auto Upgrade feature in Verifone Release 55.02:*
* *Auto Upgrade feature optimized to complete faster:*
* *If there are no changes to Operating System (OS), the OS is not reinstalled. This enables the auto upgrade to be completed faster depending on the devices at the site.*
* *If there are no schema changes, Totals Database is updated using a shell script instead of using XML and enables the auto upgrade to complete faster depending on volume of data at the site.*
* *For optimal troubleshooting of any errors occurring* during/*after Auto Upgrade, the history of Auto Upgrades are retained on the system.*
