# Upgrade Manager
The upgrade process for OpManager - installed servers across your network is simplified using the Upgrade Manager. It offers a centralised platform to manage and perform upgrades for **OpManager Standalone servers, their Failover servers.** The enhanced smart upgrade feature helps to overcome the bottlenecks faced during the upgrade process.
**Note:**
- For service pack versions **12.8.344 and above**, manual backup prerequisites are optional as the Upgrade Manager takes the backup automatically.
- The **QPM**, designed to deliver targeted patches can be seamlessly applied across services using **Upgrade Manager**, following the same steps as a service pack.
- If you are encountering issues caused by AV/EDR interactions during the upgrade process, please follow this [exclusion guide](https://www.manageengine.com/products/oputils/pgsql-av-edr-exclusion.html?upgrade-manager).
- With a successful health check, the product will now be ready for the upgrade.
- For **Failover servers,** the upgrade will start automatically for both the active and the standby server.
- Upgrade details for individual servers will be automatically updated under the **Current Status** column.
