Migrate applications from single-disk to multi-disk for Edge SWG (ProxySG) on SSP Appliances.

Issue/Introduction
Migrate your single-disk configurations to multi-disk configurations to ensure redundancy and prevent data loss. In Integrated Secure Gateway (ISG) 2.4.7.1 and later, single-disk models for Edge SWG (ProxySG) applications running on Symantec Security Platform (SSP) appliances are deprecated and are replaced with two-disk models. Existing single-disk models continue to work.
This article provides steps for migrating your applications from single-disk models to multi-disk models.
Environment
This article applies to only Edge SWG (ProxySG) applications running on SSP appliances.
Cause
Single-disk models contain one data disk and one boot disk. Multi-disk models contain two or more data disks and the boot disk. Multi-disk models ensure redundancy of system configurations if a data disk fails. Because single-disk models do not have redundancy, these models are more vulnerable to data and configuration loss than multi-disk models. To prevent data loss and (in extreme cases) your appliance from becoming inoperable, migrate your single-disk models to multi-disk models.
Resolution
With the release of ISG 2.4.7.1, single-disk models of Edge SWG (ProxySG) applications are deprecated and are replaced with new models. To determine if your model is deprecated and which model to migrate to, see the following table (the new model is listed in the same row as the deprecated model).

Migrate Applications from Single-Disk to Multi-Disk Models
Note: Before you migrate to a new model, upgrade to ISG 2.4.7.1 or later first.
To migrate a Edge SWG (ProxySG) application from a single-disk model to a multi-disk model:
- From the ISG CLI, stop the application:
(config)#applications stop app_name - Change the model to a model that uses multiple disks:
(config)# applications edit app_name model model_name - Start the application:
(config)# applications start app_name
Example
The following example shows an application (sg) being migrated from a C2S model to a C2S-B model.
(config)# applications
(config-applications)# view
