# MES Module Upgrade

**Sepasoft MES Module Suite**
 ### Upgrade MES Modules

* Upgrade from the Root of the MES Enterprise Network system down to the lowest gateway.
* 2 'hops' deep from the Root must be updated. You can then upgrade other gateways over time.

**Module Versions**

To take advantage of the data recovery and self-healing features of the Sepasoft MES Enterprise network,  the communication protocol that is installed on each server (within the Production module of the Sepasoft MES Suite) needs to be **up-to-date** and on the **same version number** **.**

Version Specific

| ![Warning](/resources/Storage/user-manual/user-manual/Warning.png) | **3.81.9 RC2** **and later** for MES Enterprise Network data recovery and self-healing features. |
| --- | --- |

If the network servers use different versions of the Sepasoft MES modules, the system uses the common-denominator protocol downgrading the features to  the oldest version of the protocol.
