 **Date available:** January 31, 2023
 
-The Azure Private 5G Core now supports multiple network slices for 5G packet core deployments. Network slices allow customers to host multiple independent logical networks in the same Azure Private 5G Core deployment. Slices are assigned to SIM policies and static IP addresses, providing isolated end-to-end networks that can be customized for different bandwidth and latency requirements.

-If you're experiencing issues with your packet core deployment, you can now re-install the packet core to return it to a known state. Re-installing the packet core deletes the existing packet core deployment and attempts to deploy the packet core at the edge with the existing site configurations. Already created **Site** dependent resources such as the **PacketCoreControlPlane**, **PacketCoreDataPlane** and **AttachedDataNetwork** will continue to be used in the deployment.

-You can check the Installation state on the **Packet Core Control Plane overview**. Upon successful redeployment, the Installation state will change from **Reinstalling** to either **Installed** or **Failed**, depending on the outcome.  You can re-install the packet core regardless if the **Installation state** is in either **Installed** or **Failed** status.
+You can check the installation state on the **Packet Core Control Plane** resource's overview page. Upon successful redeployment, the installation state will change from **Reinstalling** to either **Installed** or **Failed**, depending on the outcome. You can reinstall the packet core if the installation state is **Installed** or **Failed**.
 
-If re-install is attempted after upgrade, re-deployment would be attempted with the upgraded packet core version. The reinstallation is done using the latest packet core version currently defined in the ARM API version.

 This feature has the following limitations:
 
-- The provisioning state of resources **PacketCoreControlPlane**, **PacketCoreDataPlane** and **AttachedDataNetwork** will not change with re-install.
+- The provisioning state of resources **Packet Core Control Plane**, **Packet Core Data Plane** and **Attached Data Network** will not change with reinstall.
 - The status of the reinstallation operation can tracked only via **Activity Logs**.
-- Re-installing the packet core may take 45 minutes or more.
-- Updated Installation states are only reflected when the **Packet Core Control Plane overview** page is refreshed.
