You can upgrade Linux-based IP Office severs using a number of methods. These are:
Upgrade Method |
Description |
Subscription Mode System Upgrade |
For subscription mode IP Office systems, upgrades can be scheduled and performed remotely using Customer Operations Manager. |
Transferring an ISO file |
The new release ISO file can be transferred directly to the server. See Upgrading systems using an ISO file transfer.
The ISO transfer can be performed using a number of methods. Once the ISO file has been transferred, web manager is used to perform the upgrade. This method allows for the option of setting a scheduled upgrade. |
Upgrading from a bootable USB |
Upgrade using a USB memory key. See Upgrading using a USB key. This can be an attended or automatic upgrade.
Note:
On Avaya Solutions Platform (ASP) 110 servers, specifically Dell R640 or R660, upgrading IP Office Release to 12.3 from any previous 12.x version using the USB method is not recommended. Instead, all upgrades to 12.3 releases must be performed through Web Manager using the IP Office file transfer (ISO) method.
