 # Modify the packet core instance in a site
 
-Each Azure Private 5G Core site contains a packet core instance, which is a cloud-native implementation of the 3GPP standards-defined 5G Next Generation Core (5G NGC or 5GC). In this how-to guide, you'll learn how to modify a packet core instance using the Azure portal; this includes modifying the packet core's custom location, connected Azure Stack Edge device, and access network configuration. You'll also learn how to add and modify the data networks attached to the packet core instance.

 Additionally, the following changes don't trigger a packet core reinstall, but will require you to manually perform a reinstall to allow the new configuration to take effect:
 
-- Connecting a new Azure Stack Edge device.
+- Changing the connected ASE device.
 - Modifying the access network configuration.
 - Modifying an attached data network's configuration.
 
 If you're making any of these changes to a healthy packet core instance, we recommend running this process during a maintenance window to minimize the impact on your service. You should allow up to two hours for the process to complete.

+If your packet core instance is in **Uninstalled**, **Uninstalling** or **Failed** state, or if you're connecting an ASE device for the first time, you won't need a packet core reinstall after making your changes.
