Policy upgrade in Service Pack 2

This section describes the method by which endpoint policies are migrated to IAG 2007 SP2 from previous IAG versions, including custom policies and default policies that are provided by the system.

Upgrade of default policies

Default policies that were provided with the system in previous versions are migrated to IAG 2007 SP2 as follows:

The pre-SP2 policy is translated into the corresponding Windows policy. For example, the pre-SP2 SharePoint 2007 Download policy is translated into a SharePoint 2007 Download (Windows) policy. This is true both for policies where the default values were not edited and for policies where the default values were customized.
Mac OS and Linux policies are determined as follows:
- If a corresponding system-defined, platform-specific policy exists for a platform, it is applied as the platform's default policy. For example, SharePoint 2007 Download (Mac OS).
- If no corresponding platform-specific policy exists for a platform, the value of the policy is set to Never. For example, the default value of the SharePoint 2007 Download (Linux) policy is Never.
The default value of all the default "Other" policies is Never.

Upgrade of custom policies

Custom, user-defined policies are migrated to IAG 2007 SP2 as follows:

The pre-SP2 policy is translated into a corresponding Windows policy.
The default values of Mac OS, Linux, and Other policies are set as follows:
- In the pre-SP2 version, if the option Enforce policy only when endpoint detection is enabled was selected, then the Mac OS, Linux, and Other policies are set to Always.
- In the pre-SP2 version, if the option Enforce policy only when endpoint detection is enabled was not selected, then the Mac OS, Linux, and Other policies are set to Never.
